Subject Columns casing in Phoenix tables
Date Tue, 12 Jun 2018 01:05:00 GMT
I've gotten started with Apache Phoenix by creating some tables and running
some queries. Mostly, I've noticed that Phoenix will uppercase the column
names. However, I have one table with lowercase column names; it is named
'shapes':

I am able to run select * queries against it, but I am unable to query any
of the columns:

Note that I am using phoenix-sqlline, which runs with the following client:

/usr/hdp/2.6.5.0-292/phoenix/phoenix-4.7.0.2.6.5.0-292-client.jar

It seems like this 'shapes' table with lowercase columns is problematic and
can not be queried regardless of the casing of my query.
I am unable to create new tables similar to this existing 'shapes' table,
since any new tables that I attempt to create result in columns with upper
case columns.

Any help or insight into this issue would be appreciated.

Ali Anwar
