ruiliang created IMPALA-7562:
--------------------------------
Summary: Caused by: java.sql.SQLException:
[Cloudera][ImpalaJDBCDriver](500593) Communication link failure. Failed to
connect to server. Reason: Unknown.
Key: IMPALA-7562
URL: https://issues.apache.org/jira/browse/IMPALA-7562
Project: IMPALA
Issue Type: Bug
Components: Clients
Affects Versions: Impala 2.12.0
Environment: centOS 7
Reporter: ruiliang
Attachments: ecliseDeubgCosnle.log
I encountered a very strange problem. Spring boot configured impala JDBC query.
Under normal circumstances, all SQL queries are normal, and the statement has
no problem.However, after I restart the impala service, this exception will be
reported, or the same error code will be reported for all SQL queries. After I
have to restart my spring boot web service, all the queries will be normal
again, as I have tried many times.I looked through the server logs and found
that I did not seem to have received the request.But why is this problem so
low?Is it driven?My impala is three nodes built under CDH.
I really can not find out the reason, please help to look.thank you
