!indexes command fails because of Hive bug

[snuyanzin]

It looks like there is an Apache Hive bug which blocks output of !indexes command. The trace is below.
The suggestion is to use current value as default if java.sql.ResultSetMetaData#getColumnDisplaySize fails for any reason

by the way beeline fails in the same way
