Jarek Jarcec Cecho updated PIG-3529:
------------------------------------
Attachment: PIG-3529.patch
The issue was in following exception:
{code}
Caused by: java.lang.NullPointerException
at
org.apache.hadoop.hbase.replication.regionserver.Replication.decorateMasterConfiguration(Replication.java:295)
at org.apache.hadoop.hbase.master.HMaster.<init>(HMaster.java:461)
{code}
The problem is that property HBASE_MASTER_LOGCLEANER_PLUGINS that is being
access in Replication.java:295 is not defined when it's expected to be. I've
investigated the issue and found out that {{hbase-default.xml}} won't get it
into the configuration. So, I've added call for {{HBaseConfiguration.create}}
to propagate all HBase resources to the used configuration object. This wasn't
an issue with 0.94 and 0.95 because the code in question will be executed only
if replication is enabled which is not the case on those versions. The
replication got enabled by default in 0.96 via HBASE-9505. I don't think that
NPE is correct way how to handle this, so I'll follow up on HBase suggesting to
be more careful in the code.
Verification steps for HBase 0.95 profile:
{code}
ant clean test -Dtestcase=TestHBaseStorage -Dhbaseversion=95
-Dprotobuf-java.version=2.5.0
{code}
Verification steps for HBase 0.94 profile:
{code}
ant clean test -Dtestcase=TestHBaseStorage
{code}
I'll file a follow up JIRA to tweak the ant build for fetching proper
dependencies in order to get the HBase tests working on Hadoop 2 (e.g. that is
not included in this patch).
