Summary: EOFException for Ozone RPC client
Key: HDDS-1583
URL: https://issues.apache.org/jira/browse/HDDS-1583
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Eric Yang
We discover a bug in Ozone RPC client. If the server is in starting state, and
not completely started. Calling new SCMCLI().createScmClient(); would result
in EOFException error. Most software client have some level of retires to
establish connection without throwing errors for a brief period of time to
ensure that transient errors are not over alarming to client code. The
experience can be improved by making sure that connection logic retries a few
times before giving up. See related stack trace:
{code}java.io.EOFException: End of File Exception between local host is:
"localhost.localdomain/127.0.0.1"; destination host is:
"localhost.localdomain":9860; : java.io.EOFException; For more details see:
