I am storing and fetching rows in Hbase using Nifi Work flow. The connection to Hbase from Nifi is done by using Nifi configuration service with Hbase site.xml and core-site.xml files from Cloudera.
Service is configured properly and the flow also executes accurately with storing and fetching from Hbase but after a particular duration I get the following error.
Nifi : org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=3
Though restarting the Nifi or Hbase Master and RegionServer the issue gets resolved but again after execution of flow it appears. Tried a few solutions with adding(explicitly) znode parent, quorum, client_port, increasing the reties count.
