I'm currently running into an issue on my local setup where my application is
unable to connect to the hbase table but I'm successfully able to query the
table using hbase shell.
I'm using HTable client to make the connection and would expect to get an
error after certain retries when it's unable to establish connection.
However I'm seeing the code is continuously retrying and not logging any
error exception. I had to turn on debug to find the issue.
Is there a setting that we could use to throw an exception after certain
number of retries?
countersTable = new HTable(hbaseConfig, counters)
