@Shobhna Dhami

Can you try running the command manually as following? And check if the "testtable" exist?

# /usr/hdp/current/accumulo-client/bin/accumulo shell -u ambari-qa -p smoke
> tables

As we see the exception as following:

 ERROR: org.apache.accumulo.core.client.TableExistsException:Table testtable exists

Hence If the 'testtable' exist then try to drop it once and then re run the service check.

> droptable testtable 

.

If it still does not work then please share the Accumulo logs along with the ambari agent logs.

Also please let us know which version of Ambari Do you use? Because in very old version of ambari similar issue was reported and for enhancement, Where the issue was occurring due to already existing "testtable": https://issues.apache.org/jira/browse/AMBARI-14776

You might also want to refer to the following doc: https://community.hortonworks.com/articles/79327/re-initializing-apache-accumulo-under-hdp.html

@Jay Kumar SenSharma Thanks for the reply.

I tried to drop table testtable but getting error : Thread "shell" stuck on IO to slnxhadoop03.dhcp.noid.in:9999 (0) for at least 120348 ms

I am using HDP 2.5.3 and ambari version 2.4.2.0.
