Subject Recreating SYSTEM.CATALOG metadata
Date Sun, 28 Sep 2014 20:56:12 GMT

When I restore hbase from a backup, sqlline gets stuck unless
SYSTEM.CATALOG table is dropped. It is automatically re-created via
sqlline. However, metadata of previously created phoenix tables is lost.

So, to restore the metadata, when a 'CREATE TABLE' statement is re-issued,
Phoenix takes very, very long time to execute which I think, is because
Phoenix is upserting null value for _0 column qualifier again for every row
(billions of rows in the table).

Is there a work-around for this by somehow telling Phoenix that the
underlying table is already a Phoenix table? Using views is not an option
here. If my understanding is wrong, any pointers as to why it takes so long
for executing 'CREATE TABLE' statement is appreciated.
