you can check queue size from regionserver UI (host-address:16030/rs-status) under Queues tab. Queue size increases when there are too many requests and your RS cannot handle it. This can happen in case of too many requests (CPU crunch) ongoing compation ongoing GC You should investigate and identify the cause. and accordingly you can have more cpu, schedule compactions during off-peak hours, optimize GC. Hope it helps! ... View more

check hbase gc logs. if there is a GC pause that correlates with these log lines then you got your problem. While master/RS is in GC, it fails to send heatbeat to zookeeper and the zookeeper node expires. In that case you can increase zookeeper timeout and increase ticktime in zookeeper config. this is not directly related but do checkout: https://superuser.blog/hbase-dead-regionserver/ ... View more

good that the data is there. here's the next things you can do: 1. check table size on src cluster and snapshot size on dest cluster [hadoop dfs -du-h /apps/hbase/data/<table> or something like that] 2. compare files in snapshots that are getting listed and one which is not. What happens during copying snapshot is first data gets copied into some temp dir on dest cluster and then it gets moved to actual folder. If you see some files missing [metadata file. with .snapshot extension probably], try to search for them in other places .tmp folder as far as I remember, if you happen to find them, move it to table snapshot folder. I don't exactly remember all the dir names and locations so you will have to explore around a bit ... View more

can you confirm the owner of copied directory in destination cluster? if it is different, you may want to change it. Also check the copied data on destination cluster. the data size, the metadata file (snapshot files) and if data is present or not. sometime it is there but in different folder, probably some tmp or hidden folder, move it if that is the case ...

in that case you would want to further increase cache timeout or break your query into multiple queries and use temporary tables. ... View more
