Subject [jira] [Created] (PHOENIX-5154) 'Exception thrown when renewing lease' generates java.lang.NullPointerException
Date Thu, 21 Feb 2019 20:54:00 GMT
Hans Deragon created PHOENIX-5154:

             Summary: 'Exception thrown when renewing lease' generates java.lang.NullPointerException
                 Key: PHOENIX-5154
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.14.0
            Reporter: Hans Deragon

Got the following under,  at the cursor, doing nothing:

0: jdbc:phoenix:> 19/02/21 20:41:16 ERROR query.ConnectionQueryServicesImpl: Exception
thrown when renewing lease
        at org.apache.hadoop.hbase.client.ScannerCallableWithReplicas.setRenew(
        at org.apache.hadoop.hbase.client.ClientScanner.renewLease(
        at org.apache.phoenix.iterate.TableResultIterator.renewLease(
        at org.apache.phoenix.query.ConnectionQueryServicesImpl$
        at java.util.concurrent.Executors$

        at java.util.concurrent.ThreadPoolExecutor.runWorker(
        at java.util.concurrent.ThreadPoolExecutor$

Previously though, I got a lot of timeout exception while performing 'select count(*) from
mytable' while I was inserting in a different terminal 3 000 000 rows into it.  These exceptions
might be related.

Still, NullPointerException should never happens.  There is some bug lingering somewhere.
