Description

Final filter table:
ID  Src. Node  Tgt. Node(s)     Target type  Partition filter  Pending (Expected)  First arrived  Completed   Enabled
----------------------------------------------------------------------------------------------------------------------
 1          6          0, 1  REMOTE, REMOTE      false, false              0 (93)       50s381ms   53s566ms     false
 0          6             0          REMOTE              true              0 (93)       50s177ms   52s336ms     false

The issue is that the filter is disabled after the remote filter is sent out https://github.com/apache/impala/blob/95a1da2/be/src/runtime/coordinator.cc#L987. The code seems to really conflate releasing of resources with filters that were logically disabled.
