Description

We found that sometimes LdapImpalaShellTest#testShellLdapAuth() failed at https://github.com/apache/impala/blob/1c72c5a8f93ae3aa7e30b8bb59e0a18a654d0d34/fe/src/test/java/org/apache/impala/customcluster/LdapImpalaShellTest.java#L146 due to hitting an assertTrue() at https://github.com/apache/impala/blob/master/fe/src/test/java/org/apache/impala/customcluster/RunShellCommand.java#L50.

This test was slightly revised in IMPALA-10234. Maybe attilaj could offer some insight into it.

The corresponding log file is also provided. Let me know if other log files are needed as well. Thanks!
