catalogd using lots of memory

Explorer

Hi,

 

We are using external tables with gz files. There ara 4-5M files in a table and catalogd using whatever we give as a heap space. Currently it is using 128GB RAM. We have 600 impala nodes. Cloudera version is 5.7.0. Is there any advice to shrink the heap usage of catalogd? Why it is using that much memory?
