Rohini Palaniswamy updated PIG-4315:
------------------------------------
Assignee: Rohini Palaniswamy
Description:
TestHBaseStorage.testMergeJoin() fails. connectingLR is null in
CombinerOptimizer and throws NPE in
{code}
from.plan.getOperator(connectingLR.getOperatorKey())
{code}
When splitting DAGs and doing moveTree TezCompilerUtil.connect() overwrites the
output key of sampler LocalRearrange to the partitioner vertex.
Split followed by orderby also had issues using the same
TezCompilerUtil.connect() method.
