Niels Basjes commented on PIG-5343:
-----------------------------------
I'm still working on this because I'm having problems with what I have created
so far.
I was trying to get PIG-2599 (Mavenize Pig) running and I got stuck on a large
number of unit tests that simply fail with hard to trace errors.
Get this [https://github.com/nielsbasjes/MavenizePig] and the run.sh script
will locally create a rearranged version of the Pig source tree which compiles
pig and piggybank.
So I decided to see how the ant based build works and compare where it goes
wrong (i.e. this issue popped up to fix the docker setup to do just that)
At this point my best guess is that there is a problem in relation to the
PigServer + a 'non-local' MiniCluster and the use of HDFS which cause jobs to
fail under Java 1.8.
Try this one for example: in TestOrcStoragePushdown the BeforeClass method
createInputData the very simple pigserver job to create the test file on HDFS
fails and produces an empty file (hence all subsequent tests in that file fail
too).
It seems to be Java 1.7 / 1.8 related but at this point I'm stuck and I could
use some help/pointers where to look next.
Most importantly: Do you have these effects too?
