Zoltan Haindrich commented on HIVE-18373:
-----------------------------------------
[~minions]: looks good, could you make the test more interesting? :) ...looking
for column "a*" in {{CREATE TABLE foo(a INT)}} is not really pushing the limits
of filtering :)
... and could you also add {{show columns "\*nonexistent\*" ...}} and what
happens if the regex is invalid (for example '+' ) ?
> Make it easier to search for column name in a table

> Within a database, to filter for tables with the string 'abc' in its name, I
> can use something like:
> {code:java}
> hive> use my_database;
> hive> show tables '*abc*';
> {code}
> It would be great if I can do something similar to search within the list of
> columns in a table.
> I have a table with around 3200 columns. Searching for the column of interest
> is an onerous task after doing a {{describe}} on it.
