> Key: HBASE-6856
> URL: https://issues.apache.org/jira/browse/HBASE-6856
> Project: HBase
> Issue Type: Improvement
> Components: documentation
> Affects Versions: 0.92.0
> Reporter: Daniel Iancu
> Assignee: Daniel Iancu
> Labels: LeaseException
> Fix For: 0.96.0
>
>
> In some situations clients that fetch data from a RS get a LeaseException
> instead of the usual ScannerTimeoutException/UnknownScannerException.
> This particular case should be documented in the HBase guide.
> Some key points
> * the source of exception is:
> org.apache.hadoop.hbase.regionserver.Leases.removeLease(Leases.java:230)
> * it happens in the context of a slow/freezing RS#next
> * it can be prevented by having hbase.rpc.timeout >
> hbase.regionserver.lease.period
> Harsh J investigated the issue and has some conclusions, see
