Description
多线程进行查询,其中会出现错误,如下所示
`org.apache.iotdb.rpc.StatementExecutionException: 500: [INTERNAL_SERVER_ERROR(500)] Exception occurred: "select * from root.js.3205.320583.SNS00003489 where time >= 1650758400000 and time< 1650760200000". executeQueryStatement failed. java.lang.NullPointerException
at org.apache.iotdb.rpc.RpcUtils.verifySuccess(RpcUtils.java:94)
at org.apache.iotdb.rpc.RpcUtils.verifySuccessWithRedirection(RpcUtils.java:115)
at org.apache.iotdb.session.SessionConnection.executeQueryStatement(SessionConnection.java:341)
at org.apache.iotdb.session.Session.executeStatementMayRedirect(Session.java:646)
at org.apache.iotdb.session.Session.executeQueryStatement(Session.java:618)`
但是我单独将这条语句拿出来进行单元测试时未报错
Contributor guide
Research direction
Start by reproducing the failure with the reported multi-threaded query, then trace the stack through org.apache.iotdb.rpc.RpcUtils.java, SessionConnection.java, and Session.java at the reported methods. Compare the concurrent run with the standalone unit test; done means the concurrent failure is explained and covered by a regression test or the issue is narrowed to a reproducible cause.
