Subject [jira] [Commented] (YARN-4234) New put APIs in TimelineClient for ats v1.5
Date Wed, 18 Nov 2015 00:01:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15009877#comment-15009877

Li Lu commented on YARN-4234:
-----------------------------

Hi [~xgong], the current fix will force to close the current FD if the incoming write request
is to a different entity group. This may generate a lot of files since users may switch to
different entity groups arbitrarily. Meanwhile, we're changing the content of the concurrent
hash table, but not enforcing strong consistency. Maybe we'd like to switch the hash map to
use entity group id for each FDs?
