Rushabh S Shah commented on HBASE-21521: ---------------------------------------- Is this feature/improvement still required ? I would like to contribute to this jira if no one else is working on it. My front end skills are not that sharp but if no one else volunteers I will try to refine them. Initially I can expose all the jmx metrics and then work on adding them to web ui. Please suggest. > 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 Purtell > Priority: Major > > 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 (v8.3.2#803003)
