-------------------------------
Summary: POReservoirSample should handle endOfAllInput flag
Key: PIG-3786
URL: https://issues.apache.org/jira/browse/PIG-3786
Project: Pig
Issue Type: Sub-task
Components: tez
Affects Versions: tez-branch
Reporter: Daniel Dai
Assignee: Daniel Dai
Fix For: tez-branch
POReservoirSample assumes it always get STATUS_OK until it hits STATUS_EOP,
means all inputs finished. This is not true if the plan also contains a
POStream, since POStream will issue a STATUS_EOP even if inputs are not
exhausted. Need to make POReservoirSample handles STATUS_EOP and endOfAllInput
flag. This cause e2e test failure such as ComputeSpec_3.
POPoissonSample should do the same.
