to look at the new patch set (#2).
Change subject: IMPALA-10076: Reduce partition level update logs

IMPALA-10076: Reduce partition level update logs
Catalogd and the legacy mode coordinator log catalog topic items one by
a line. A table can have more than 100K partitions. It's too verbose to
log all partition level updates. This patch aggregates the partition
level updates of each table and only logs the aggregated info in a line.
For instance, here is an aggregated log:
Collected 24 partition update(s):
1:HDFS_PARTITION:test.tbl:(p=1,p=2,...,p=24), version=1451, original
size=(avg=646, min=646, max=648, sum=15516), compressed size=(avg=478,
min=475, max=485, sum=11487)
If there are more than 3 partitions, we only show the smallest, the
second smallest and the largest partition names. If there are only one
partition update, the log format is the same as before:
Collected 1 partition update(s): 1:HDFS_PARTITION:test.tbl:p=0,
version=1451, original size=648, compressed size=475
To support these, this patch implements a helper class,
PartitionMetaSummary, to aggregate these information and get a summary
for logging. The compressed size is calculated by BE. So the jni method
for NativeAddPendingTopicItem is extended to return the actual
compressed size.
Tests:
- Added unit tests for PartitionMetaSummary.
- Start the cluster in mixed catalog mode and manually verified the
logs.
