Subject [jira] Commented: (HADOOP-4498) JobHistory does not escape literal jobName when used in a regex pattern
Date Fri, 24 Oct 2008 04:45:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12642376#action_12642376
] 

Amar Kamat commented on HADOOP-4498:
------------------------------------

Chris,
Can you help us reproduce this bug? What should be the jobname which can lead to this issue?
Plz include a testcase which
{code}
1) Submits a job with the *special* job name
2) Check if the job submission succeeds 
{code}
This test should fail without the fix.
