Description

Based on its property description in HiveConf and the comments in HIVE-12650 (https://issues.apache.org/jira/browse/HIVE-12650?focusedCommentId=15128979&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15128979), hive.spark.client.connect.timeout is the timeout when the spark remote driver makes a socket connection (channel) to RPC server. But currently it is also used by the remote driver for RPC client/server handshaking, which is not right. Instead, hive.spark.client.server.connect.timeout should be used and it has already been used by the RPCServer in the handshaking.
The error like following is usually caused by this issue, since the default hive.spark.client.connect.timeout value (1000ms) used by remote driver for handshaking is a little too short.
