Ramesh Kumar Thangarajan commented on HIVE-22889:
-------------------------------------------------
Yes sure, when we hit the webhcat url with parameters for a query like below:
{code:java}
curl -i -k -v --negotiate -u : -X PUT -H Content-type:application/json -d
'{"ifNotExists":"true","columns":[{"name":"archreqtsn","type":"decimal(23,0)","comment":"{DATATYPE:DEC}"}],"format":{"storedAs":"ORC"},"external":"true","location":"/tmp/table1","partitionedBy":[{"name":"`archpartid`","type":"string","comment":""}]}'
{code}
we used to trim the leading and trailing quotes for all the argument values and
for the entire query in hcatalog(commons-cli) 1.2. In commons-cli 1.4, there
was a change which restricts the trimming of leading and trailing quotes
https://issues.apache.org/jira/browse/CLI-185. hcat-cli was dependent on this
function from removing the quotes. But unfortunately with the upgrade from 1.2
to 1.4 for commons-cli, it will no longer trim if there are any quotes in
between the strip(apart from the leading and trailing quotes). Because there
are malformed queries(with extra quotes at the front and back) passed to hive
from hcat cli if the query contains quotes. In this change I am trying redo the
function at
[https://github.com/apache/commons-cli/blob/master/src/main/java/org/apache/commons/cli/Util.java#L63]
in hcat cli, with restricted condition check. My My concern if we do this
change on the
[https://github.com/apache/commons-cli/blob/master/src/main/java/org/apache/commons/cli/Util.java#L63],
then we might end up causing regressions on whoever using the commons-cli. So
I anded up with this patch.
