> Streaming debug output outputs null input-split information

> Key: PIG-1702
> URL: https://issues.apache.org/jira/browse/PIG-1702
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.7.0
> Reporter: Adam Warrington
> Assignee: Adam Warrington
> Priority: Minor
> Fix For: 0.10

> Attachments: PIG-1702-0.patch

>
> Within the Pig streaming command execution, debug information is printed out
> to stderr which specified the input file, as well as split information. The
> function is
> org.apache.pig.backend.hadoop.streaming.HadoopExecutableManager.writeDebugHeader().
> Pig 0.7 outputs null for the split file, and -1 for the split start-offset
> and split length. Example output:
> ===== Task Information Header =====
> Command: test.pl
> (stdin-org.apache.pig.builtin.PigStreaming/stdout-org.apache.pig.builtin.PigStreaming)
> Start time: Mon Oct 25 21:24:45 EDT 2010
> Input-split file: null
> Input-split start-offset: -1
> Input-split length: -1
> Within the writeDebugHeader() function, the input file information is
> obtained by querying for the "map.input.file" configuration variable. This
> configuration variable was set by the old hadoop m/r api, but not by the 0.20
> api, which Pig 0.7 now uses. The new way to get this information is with
> something like: ((FileSplit) context.getInputSplit).getPath(). See
> HADOOP-5973.
