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.
