Rohini Palaniswamy commented on HCATALOG-301:
---------------------------------------------
HCat keeps all the table names in lowercase even if the table was created with
upper case. But when we setup the znodes for revision mgmt during table
creation we don't make it lower case. That is causing the problem. Will fix
after confirming with team that HCat will always handle database and table
names in
lower case.
> Reading from a table without snapshot throws bad error.
