Xiaolin Ha updated HBASE-21521: ------------------------------- Fix Version/s: 2.6.0 2.5.1 3.0.0-alpha-4 2.4.15 > Expose master startup status via JMX and web UI > ----------------------------------------------- > > Key: HBASE-21521 > URL: https://issues.apache.org/jira/browse/HBASE-21521 > Project: HBase > Issue Type: Improvement > Components: master, UI > Reporter: Andrew Kyle Purtell > Assignee: Xiaolin Ha > Priority: Major > Fix For: 2.6.0, 2.5.1, 3.0.0-alpha-4, 2.4.15 > > Attachments: hbase-21521-1.png, hbase-21521-2.png, hbase-21521-3.png, > hbase-21521-4.png, hbase-21521-revised-1.png, hbase-21521-revised-2.png > > > Add an internal API to the master for tracking startup progress. Expose this > information via JMX. > Modify the master to bring the web UI up sooner. Will require tweaks to > various views to prevent attempts to retrieve state before the master fully > up (or else expect NPEs). Currently, before the master has fully initialized > an attempt to use the web UI will return a 500 error code and display an > error page. > Finally, update the web UI to display startup progress, like HDFS-4249. > Filing this for branch-1. Need to check what if anything is available or > improved in branch-2 and master. -- This message was sent by Atlassian Jira (v8.20.10#820010)
