[jira] [Updated] (IMPALA-11700) impala-shell fails to print the exception due to missing 'inner' attribute in TTransportException
[ https://issues.apache.org/jira/browse/IMPALA-11700?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Quanlong Huang updated IMPALA-11700:
------------------------------------
Description:
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'

Welcome to the Impala shell.
(impala shell build version not available)
You can change the Impala daemon that you're connected to by using the CONNECT
command.To see how Impala will plan to run your query without actually executing
it, use the EXPLAIN command. You can change the level of detail in the EXPLAIN
output by setting the EXPLAIN_LEVEL query option.

Run the PROFILE command after a query has finished to see a comprehensive summary
of all the performance and diagnostic information that Impala gathered for that
query. Be warned, it can be very long!

So probably we should check whether TTransportException has the 'inner' attribute before using it.
