[jira] [Updated] (DRILL-1403) HBase predicate pushdown filters are
not getting applied

Attachment: 0001-DRILL-1403.patch
Can anyone please review. I verified in few cases.
This patch is working for below queries(with select * ).
{noformat}
SELECT * FROM hbase.`students1` t where t.account.name = 'Bob' AND t.address.zipcode = '12345'
SELECT * FROM hbase.`students1` t where t.account.name = 'Bob' AND t.address.zipcode = '12345' OR t.account.name = 'Frank' OR t.account.name = 'Mary'
SELECT * FROM hbase.`students1` t where t.account.name = 'Bob' OR t.account.name = 'Frank' OR t.account.name = 'Mary' OR t.account.name = 'Alice'
{noformat}
But when we select any field like below, then it's not even calling HBasePushFilterIntoScan.matches. Is this expected?
{noformat}
SELECT CAST(account['name'] as VarChar(20)), CAST (address['state'] as VarChar(20)), CAST (address['street'] as VarChar(20)), CAST (address['zipcode'] as VarChar(20)) FROM hbase.`students`
{noformat}
