Subject [jira] [Updated] (TEZ-3115) Shuffle string handling adds significant memory overhead
Date Mon, 29 Feb 2016 16:59:18 GMT

     [ https://issues.apache.org/jira/browse/TEZ-3115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jonathan Eagles updated TEZ-3115:
    Attachment: TEZ-3115.3.patch

[~rajesh.balamohan], addressed the extra string construction. Also, refactored out the no
longer used constructBaseURIForShuffleHandler to remove an additional string constriction
for host:port. Let me know if this is sufficient. I don't think this introduces a backwards
compatibility issue.

> While investigating the OOM heap dump from TEZ-3114 I noticed that the ShuffleManager
and other shuffle-related objects were holding onto many strings that added up to over a hundred
megabytes of memory.
