---------------------------------
Summary: Avoid coordinator loading useless HDFS table’s partition
metadata.
Key: IMPALA-12067
URL: https://issues.apache.org/jira/browse/IMPALA-12067
Project: IMPALA
Issue Type: Bug
Reporter: Zhi Tang
Although catalogd propagates incremental metadata updates at the partition
level, the coordinators still loads all of the table's partition metadata at
query time, even if it is not being used. This is caused by coor needing to
calculate the total hdFsbytes of the HDFS table. This can be optimized by
transferring the computational logic to catalogd.
