Subject [jira] Commented: (HADOOP-5721) Provide EditLogFileInputStream and EditLogFileOutputStream as independent classes
Date Tue, 05 May 2009 17:31:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12706119#action_12706119
] 

Hemanth Yamijala commented on HADOOP-5721:
------------------------------------------

I don't think the failure is related to this patch at all and shouldn't hold commit of this
patch.

I committed a change to capacity scheduler (HADOOP-5726) which changed the capacity scheduler
config template file (capacity-scheduler.xml.template). At build time, in a clean workspace,
the template file is copied to become the capacity-scheduler.xml file. But this does not happen
if the file already exists (as it could in an existing workspace). In such a case, the new
code is looking for some config properties that changed in HADOOP-5726, which are not found
in the older capacity-scheduler.xml file and hence fails. 

I don't know how this can be fixed without changing the logic by which the build script copies
the template files to the actual files. Any ideas, Nigel ?

> EditLogFileInputStream and EditLogFileOutputStream are currently part of FSEditLog. With
this patch we want to extract them and provide as independent classes.
