Tim Armstrong commented on IMPALA-9090:
---------------------------------------
[~Xiaomeng Zhang] that's in the embedded explain plan, we want it in the actual
scan node in the profile, like this bit:
{noformat}
HDFS_SCAN_NODE (id=2):(Total: 1s194ms, non-child: 1s194ms, % non-child:
100.00%)
- BytesRead: 0

> Scan node in HDFS profile should include name of table being scanned

> Assignee: Xiaomeng Zhang
> Priority: Critical
>
> The only way to figure out the table being scanned by a scan node in the
> profile is to pull the string out of the explain plan or execsummary. This is
> awkward, both for manual and automated analysis of the profiles. We should
> include the table name as a string in the SCAN_NODE implementation.
