Understanding incompatibilities with different versions of hadoop?
Jonathan Coveney 2011-05-03, 15:13
I was wondering if there was any documentation around (or if anyone simply knew) which versions of pig work with which versions of Hadoop? We are now using 0.20.2 CDH3 and it is not compatible with the pig trunk...I'm hoping to understand why.
Thanks Jon

We, the Yahoo Pig team, test Pig against 0.20.2 Hadoop and the internal Yahoo version of Hadoop (hopefully soon to be released through Apache as 0.20.203). My impression of CHD3 was that it was very close to 0.20.203 with HDFS append added. The Cloudera guys would better be able to answer what changes in CDH3 make it not compatible with Pig trunk. They also give a list of patches that they apply that makes their release different from the official Apache version. You could look through the patches they applied to Pig 0.8 to see what they needed to make it work with their version of 0.20.
Alan.

Hi Jonathan,
I compiled Pig trunk jarwithouthadoop.jar and it works fine with CDH3 (Add CDH3 libs to classpath). I think CDH3 pig version is 0.7.
Thanks, Aniket
