FAQ
Hi,

I am running into a problem starting Impala. The cluster is on
CDH5-b1(parcels) on Ubuntu 12.04 and has bunch of databases and tables
created by hive. When I start Impala service, I see the error pasted below
and I am unable to access hive database/tables. Any idea how I can fix this
? Also, let me know if there's additional info that would be useful in
debugging.


*Error from Impala shell:*

[xxxxxxxl:21000] > show tables;

Query: show tables

ERROR: AnalysisException: This Impala daemon is not ready to accept user
requests. Status: Waiting for catalog update from the StateStore.
