How to configure ‘‑‑enable_orc_scanner’ to ture in cloudera manager 6.3, my impala version is 3.2

Question

In cdh6.3.0, the version of impala is 3.2. Impala can support files in ORC format, but you need to set ‑enable_orc_scanner to true.

How do I set this property in the Cloudera manager console?

Answer 1

Based on Impala documentation you need to add that flag, possibly to IMPALA_SERVER_ARGS environment variable on the Impala Daemons.

I'm not sure Cloudera Manager exposes such settings.

Note: Just because you have Cloudera Manager, does not mean you can configure each little detail on the nodes; you might need to SSH to individual machines.

Answer 2

In Cloudera Manager , navigate to Clusters > Impala .

In the Configuration tab, set --enable_orc_scanner=true in the Impala Command Line Argument Advanced Configuration Snippet (Safety Valve)field
