Description
During Master startup if quota feature is enabled and region server is running TableNotFoundException occurs in regionServer logs
SpaceQuotaRefresherChore does not checks whether hbase:quota table is present,before starting its operation which sometimes may result to TableNotFoundExceptions like below.
This is because master has not created the hbase:quota table and SpaceQuotaRefresherChore is running.
java.io.UncheckedIOException: org.apache.hadoop.hbase. TableNotFoundException: hbase:quota at org.apache.hadoop.hbase.client.ResultScanner$1.hasNext(ResultScanner.java:55) at org.apache.hadoop.hbase.quotas.SpaceQuotaRefresherChore.fetchSnapshotsFromQuotaTable(SpaceQuotaRefresherChore.java:170) at org.apache.hadoop.hbase.quotas.SpaceQuotaRefresherChore.chore(SpaceQuotaRefresherChore.java:84) at org.apache.hadoop.hbase.ScheduledChore.run(ScheduledChore.java:186) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at org.apache.hadoop.hbase.JitterScheduledThreadPoolExecutorImpl$JitteredRunnableScheduledFuture.run(JitterScheduledThreadPoolExecutorImpl.java:111) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748)
