Pengcheng Xiong commented on HIVE-14143:
----------------------------------------
[~nemon], I think we only need to see if it is possible to improve your first
patch regarding the "// Set READ_ALL_COLUMNS to false
"
Right now, you have
{code}
111 if (ids.size() > 0) {
112 // Set READ_ALL_COLUMNS to false
113 conf.setBoolean(READ_ALL_COLUMNS, false);
114 }
113 } 115 }
{code}
I would like to know if it is possible to change it to the following to be
consistent with the definition we have in TableScanDesc.java:
{code}
111 if (ids == null || ids.size() != *sizeOfColumnsInTableScan*) {
112 // Set READ_ALL_COLUMNS to false
113 conf.setBoolean(READ_ALL_COLUMNS, false);
114 }
113 } 115 }
{code}
Then you do not need to modify the TestColumnProjectionUtils.java. Thanks.
