Michael Smith closed IMPALA-11700.
----------------------------------
Resolution: Won't Fix
Weird dev issue and no longer supporting Python 2.
> impala-shell fails to print the exception due to missing 'inner' attribute in
> TTransportException

> Key: IMPALA-11700
> URL: https://issues.apache.org/jira/browse/IMPALA-11700
> Project: IMPALA
> Issue Type: Bug
> Reporter: Quanlong Huang
> Priority: Major
>
> There are some issues in my impalads so my impala-shell can't connet to them.
> However, the error message is not printed correctly. What it said is
> {noformat}
> Error connecting: AttributeError, 'TTransportException' object has no
> attribute 'inner'
> {noformat}
> I'm using Python2. Here is the full output:
> {noformat}
> $ bin/impala-shell.sh
> Starting Impala Shell with no authentication using Python 2.7.16
> Opened TCP connection to localhost:21050
> Error connecting: AttributeError, 'TTransportException' object has no
> attribute 'inner'

> CC [~MikaelSmith] since the code is added in IMPALA-11389.
