I tried your code. there seems have a bug.
e.getMessage may get a null value, which may cause NPE in ThriftServerPage.errorMessageCell(detail)

[BruceXu1991]

This PR still occurs in Spark 2.2.1. A workaround is to use "String.valueOf(e.getMessage)" instead of "e.getMessage" to avoid of NPE problem.

[cenyuhai]

ok, but My pr is closed by community...

[cenyuhai]

please catch the exception in ThriftServerPage.errorMessageCell. Without my pr, that function still throw exception.
