VMware’s Serengeti Brings Hadoop to Virtual, Cloud Environments

Posted on by

Hadoop is a framework for reliably running applications on large hardware clusters. Many large enterprises (such as Facebook and IBM) have come to rely on it as a vital part of their respective data-crunching infrastructures. Research firm IDC recently predicted that worldwide revenues from Hadoop and MapReduce, another framework for processing problems across huge datasets, could hit $812.8 million in 2016, a significant uptick from $77 million in revenues last year.

VMware has positioned Serengeti as a “one click” deployment toolkit that, when used in conjunction with its vSphere platform, can deploy an enterprise-level Hadoop cluster in a matter of minutes. The company claims that vSphere’s virtualization capabilities will boost the “availability and manageability” of Hadoop clusters.

Serengeti is an open source project initiated by VMware to enable the rapid deployment of an Apache Hadoop cluster HDFS, MapReduce, Pig, Hive, .. on a virtual platform.

Serengeti 0.5 currently supports vSphere, with the ability to support other platforms. The project is at an early stage, and is endorsed by all major Hadoop distributions including Cloudera, Greenplum, Hortonworks and MapR.

European ISPs Lobby ITU Against Net Neutrality

Posted on by

ETNO’s submission to the ITU sets out a difference between “end to end quality of service delivery” and “best-effort delivery”, and says operators should get “fair compensation”,  concluding that “nothing shall preclude” commercial agreements based on differentiated service.

Net Neutrality advocates say charging for services would allow providers to kill off competitors that run on top of their networks, like VoIP services such as Skype that operate over networks and compete with telephone services. The question also raises fears of Internet taxes.

“mount.nfs4: Operation not permitted” when mounting NFS device

Posted on by

This is a configuration issue. A required parameter needs to be added to the file /etc/exports to define the root file system for mounting.

The parameter that needs to be added follows:

fsid=0

An example line would look like the following:

/storage *(rw,fsid=0,sync,insecure_locks,insecure,no_root_squash)

Additional information

NFSv4 works differently and no longer references the root of the file system but instead requires the root to be defined with fsid=0.

If fsid=0 is not present, permission will never be granted for the file system to be mounted.

via RHEL6: “mount.nfs4: Operation not permitted” when mounting NFS device – IBM System Cluster 1350 (1410).

NFS4 is different.   After configuring exportfs the old fashioned way the nfs mounts did not work at all.  I narrowed it down to the CentOS server running nfs4 and then found this article from IBM.  It seems to work now.

CentOS 64 bit bad ELF interpreter

You’re on a 64-bit system, and don’t have 32-bit library support installed.

sudo yum install glibc.i686

via linux – CentOS 64 bit bad ELF interpreter – Stack Overflow.

Also had to yum install gtk2.i686.  Here’s the solution from the above link for  Debian based systems:

Updated: Since it seems this answer is still getting viewed, and occassionally up-voted, note that the solution above works on CentOS, Fedora, or Red Hat derived operating systems; on a Debian or Ubuntu derived system, however, one would instead use

 sudo apt-get install ia32-lib

For some reason, after all these years of using 64 bit OSs, and still having an active, running FC10 installation, this was the first time I had no choice but to run a 32-bit app on a 64 bit machine.
The above solution worked

The Future Fruits Of Apple + Facebook

Posted on by

And while Facebook is struggling to make money on small mobile screens, Facebook TV could be a more natural place for display ads. Advertisers have been demanding a bigger, flashier ad formats that Facebook TV could host. We’re so used to watching commercials on TV that a glossy still ad every 10 minutes or 10 photos, or the occasional fifteen-second pre-roll might not seem out of place.

Apple would gain a good showcase for how existing mobile and web apps could be reformatted for the television. The special Facebook app could also be a selling point for Apple’s new TV hardware. Facebook needs to be on televisions and Apple needs Facebook on its televisions, so this collaboration seems inevitable if not imminent.

What goes around comes around.  The first computer to use the TV as a monitor was the VIC-20 or Commodore 64.  Then there was WebTV.  Now Apple wants to pipe Facebook to TV? Not having a TV or a Facebook account I have no basis for an opinion on this.

Which carcass is worth more for Microsoft’s vultures, RIM or Nokia?

Nokia and RIM, the two former leaders in the early smartphone market, are now basically at the end stage of their downward spirals. This is an opportunity for Microsoft, which wants to make some inroads in the smartphone market, assuming Microsoft it can play its cards right.

Researcher: Interdependencies could lead to cloud ‘meltdowns’

Ford compared this scenario to the intertwining, complex relationships and structures that helped contribute to the global financial crisis.

New cloud services may arise that essentially “resell, trade, or speculate on complex cocktails or ‘derivatives’ of more basic cloud resources and services, much like the modern financial and energy trading industries operate,” he wrote.

Android Open Source

Posted on by

Here you can find the information and source code you need to build an Android-compatible device.

Android is an open-source software stack for mobile devices, and a corresponding open-source project led by Google. We created Android in response to our own experiences launching mobile apps. We wanted to make sure that there was no central point of failure, so that no industry player can restrict or control the innovations of any other. That’s why we created Android, and made its source code open.

From:Android is about to get a lot faster thanks to Linaro

The folks behind the Linaro open source software project have put a little time into tweaking Google Android to use the gcc 4.7 toolchain. The result is a version of Android that can perform many tasks between 30 and 100 percent faster than the version of Android Google 4.0 Google currently offers through the AOSP (Android Open Source Project).
