[jira] [Updated] (TEZ-2544) Incorrect dag result due to wrong
TaskSpec in recovering
[ https://issues.apache.org/jira/browse/TEZ-2544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jeff Zhang updated TEZ-2544:
----------------------------
Description:
Expected TaskSpec
{noformat}
DAGName : OrderedWordCount, VertexName: Summation, VertexParallelism: 1, TaskAttemptID:attempt_1433850314856_0019_1_01_000000_0, processorName=org.apache.tez.examples.OrderedWordCount$SumProcessor, inputSpecListSize=1, outputSpecListSize=1, inputSpecList=[{{ sourceVertexName=Tokenizer, physicalEdgeCount=2, inputClassName=org.apache.tez.runtime.library.input.OrderedGroupedKVInput }}, ], outputSpecList=[{{ destinationVertexName=Sorter, physicalEdgeCount=1, outputClassName=org.apache.tez.runtime.library.output.OrderedPartitionedKVOutput }}
{noformat}
The actual TaskSpec
{noformat}
DAGName : OrderedWordCount, VertexName: Summation, VertexParallelism: 1, TaskAttemptID:attempt_1433850314856_0019_1_01_000000_0, processorName=org.apache.tez.examples.OrderedWordCount$SumProcessor, inputSpecListSize=1, outputSpecListSize=1, inputSpecList=[{{ sourceVertexName=Tokenizer, physicalEdgeCount=1, inputClassName=org.apache.tez.runtime.library.input.OrderedGroupedKVInput }}, ], outputSpecList=[{{ destinationVertexName=Sorter, physicalEdgeCount=1, outputClassName=org.apache.tez.runtime.library.output.OrderedPartitionedKVOutput }}
{noformat}
The expected physicalEdgeCount is 2 but actually it is 1, it happens when dynamic parallelism estimation is enabled.
