Subject [jira] Commented: (HADOOP-5623) Streaming: process provided status messages are overwritten every 10 seoncds
Date Mon, 25 May 2009 05:36:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712642#action_12712642
] 

Jothi Padmanabhan commented on HADOOP-5623:
-------------------------------------------

Changes look fine.
However, the test case fails. That is because HADOOP-5572 introduced progress phases for the
map task too, so the status messages get appended by " > whichphase". In TestStreamingStatus,
reports[0].getState is returning "starting echo > sort"  which is different from the expected
string.

> Every 10 seconds (if the streaming process is producing output key/values on stdout),
PipeMapRed sets the task's status string to "Records R/W=N/N". This replaces any custom task
status that the streaming process may have specified using the "reporter:status:" stderr lines.
