Subject [jira] [Updated] (YARN-1514) Utility to benchmark ZKRMStateStore#loadState for ResourceManager-HA
Date Mon, 16 Feb 2015 19:54:12 GMT

     [ https://issues.apache.org/jira/browse/YARN-1514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tsuyoshi OZAWA updated YARN-1514:
---------------------------------
    Attachment: YARN-1514.7.patch

* Fixing the bug of state management(cleanup works well).
* Removing ZK_TIMEOUT_MS.
* Using ContainerId.newContainerId instead of ContainerId.newInstance.
* Fixing up default values more naturally: ZK_PERF_NUM_APP_DEFAULT is 1000, ZK_PERF_NUM_APPATTEMPT_PER_APP
is 10.

About the excessive log messages, it can be suppressed with hadoop --loglevel option:

{code}
$ bin/hadoop --loglevel fatal jar ../../../hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/target/hadoop-yarn-server-resourcemanager-3.0.0-SNAPSHOT-tests.jar
TestZKRMStateStorePerf -appSize 5 -appAttemptSize 10 -workingZnode /Test3
ZKRMStateStore takes 39 msec to loadState.
{code}

> ZKRMStateStore is very sensitive to ZNode-related operations as discussed in YARN-1307,
YARN-1378 and so on. Especially, ZKRMStateStore#loadState is called when RM-HA cluster does
failover. Therefore, its execution time impacts failover time of RM-HA.
> We need utility to benchmark time execution time of ZKRMStateStore#loadStore as development
tool.
