bq. Can I manually remove this znodes, or do I need to do this through yarn command line?
Which version of hadoop you are using ? If the version is 2.6 or after 2.6, you could do yarn resourcemanager -format-state-store which will format all the rmstore (basically delete path ha/testhbase1/rmstore/ZKRMStateRoot and all the subdir/files) Thanks Xuan Gong On 7/8/15, 5:45 AM, "Akmal Abbasov" <[email protected]> wrote: >> But I¹ve noticed that there are ~4000 znodes in >>/hadoop-ha/testhbase1/rmstore/ZKRMStateRoot/RMAppRoot in Zookeeper. >Can I manually remove this znodes, or do I need to do this through yarn >command line? > >Thank you. > >> On 07 Jul 2015, at 10:23, Akmal Abbasov <[email protected]> >>wrote: >> >> Hi all, >> I have HBase cluster. >> I run a cron job each hour to create a snapshot of tables in HBase and >>export these snapshots to another HBase cluster for backup. >> But I¹ve noticed that there are ~4000 znodes in >>/hadoop-ha/testhbase1/rmstore/ZKRMStateRoot/RMAppRoot in Zookeeper. >> What are these znodes? >> Are they failed yarn applications? >> How I need to handle them? >> >> Thank you. >> Akmal >
