Stuck as query from Java hangs through JDBC


Stuck as query from Java hangs through JDBC

New Contributor

Here is what is happening:


I am having a weird issue.   I try to run query into Impala from Java and it hangs.  I run same text in Hue and it works.  I figure it’s a non-printable character and remove all of them before issuing query.  Still hangs.  No exception bubbles up, sits there for an hour.  No evidence of query within Cloudera Manager I am at a loss. .  I can't trying to automate query submission for A/B testing.  I tried setting Simba JDBC logging through connection string and that did nothing.  No logs on my machine were created.  


Is there any characters I should be looking out for for?  I removed all non-printable characters.
