I'm getting this warning in the start up of impala-shell:
/opt/cloudera/parcels/CDH-5.8.0-1.cdh5.8.0.p0.42/lib/impala-shell/ext-py/sasl-0.1.1-py2.7-linux-x86_64.egg/_saslwrapper.py:3: UserWarning: Module backports was already imported from None, but /usr/lib/python2.7/site-packages is being added to sys.path
Tried with the impala administrator user and a client user, and I got the same warning. What is this warning?.
It sounds like you're using an old unsupported version of IMPALA_KUDU. Could you please upgrade to Impala from CDH 5.10 and see if the problem persists? We are no longer supporting these beta releases of the Impala-Kudu integration now that the "stock" Impala in CDH 5.10 natively supports Kudu.
