Anirudh Todi updated HBASE-4168: -------------------------------- Attachment: HBASE-4168-revised.patch > A client continues to try and connect to a powered down regionserver > -------------------------------------------------------------------- > > Key: HBASE-4168 > URL: https://issues.apache.org/jira/browse/HBASE-4168 > Project: HBase > Issue Type: Bug > Reporter: Anirudh Todi > Assignee: Anirudh Todi > Priority: Minor > Attachments: HBASE-4168-revised.patch, HBASE-4168.patch > > > Experiment-1 > Started a dev cluster - META is on the same regionserver as my key-value. I > kill the regionserver process but donot power down the machine. > The META is able to migrate to a new regionserver and the regions are also > able to reopen elsewhere. > The client is able to talk to the META and find the new kv location and get > it. > Experiment-2 > Started a dev cluster - META is on a different regionserver as my key-value. > I kill the regionserver process but donot power down the machine. > The META remains where it is and the regions are also able to reopen > elsewhere. > The client is able to talk to the META and find the new kv location and get > it. > Experiment-3 > Started a dev cluster - META is on a different regionserver as my key-value. > I power down the machine hosting this regionserver. > The META remains where it is and the regions are also able to reopen > elsewhere. > The client is able to talk to the META and find the new kv location and get > it. > Experiment-4 (This is the problematic one) > Started a dev cluster - META is on the same regionserver as my key-value. I > power down the machine hosting this regionserver. > The META is able to migrate to a new regionserver - however - it takes a > really long time (~30 minutes) > The regions on that regionserver DONOT reopen (I waited for 1 hour) > The client is able to find the new location of the META, however, the META > keeps redirecting the client to powered down > regionserver as the location of the key-value it is trying to get. Thus the > client's get is unsuccessful. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
