---------------------------------------
Summary: Usage of HiveClient not threadsafe.
Key: SPARK-2485
URL: https://issues.apache.org/jira/browse/SPARK-2485
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Michael Armbrust
Assignee: Michael Armbrust
When making concurrent queries against the hive metastore, sometimes we get an
exception that includes the following stack trace:
{code}
Caused by: java.lang.Throwable: get_table failed: out of sequence response
at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:76)
at
org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.recv_get_table(ThriftHiveMetastore.java:936)
{code}
Likely, we need to synchronize our use of HiveClient.
