node health check script does not display the correct message on timeout ------------------------------------------------------------------------
Key: MAPREDUCE-709 URL: https://issues.apache.org/jira/browse/MAPREDUCE-709 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 0.21.0 Reporter: Ramya R Priority: Minor Fix For: 0.21.0 When the node health check script takes more than "mapred.healthChecker.script.timeout" to return, it should display a timeout message. Instead it displays the full stacktrace as below: {noformat} java.io.IOException: Stream closed at java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:145) at java.io.BufferedInputStream.read(BufferedInputStream.java:308) at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:264) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158) at java.io.InputStreamReader.read(InputStreamReader.java:167) at java.io.BufferedReader.fill(BufferedReader.java:136) at java.io.BufferedReader.readLine(BufferedReader.java:299) at java.io.BufferedReader.readLine(BufferedReader.java:362) at org.apache.hadoop.util.Shell.runCommand(Shell.java:202) at org.apache.hadoop.util.Shell.run(Shell.java:145) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:338) at org.apache.hadoop.mapred.NodeHealthCheckerService$NodeHealthMonitorExecutor.run(NodeHealthCheckerService.java:119) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) {noformat} Also the "mapred.healthChecker.script.timeout" is not being reflected in the job.xml. It always picks up the default value. It is just an UI issue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
