Kudu leader master uses too much memory

[#1]

Hello!

I'm using kudu as my data store.

But kudu leader master uses too much memory(about 30GB), and other masters and tablet servers uses much less(about 2GB).

Leader master's memory usage

Follower master's memory usage

Kudu Master spec:

• 3 nodes
• 16GB physical memory per master
• 32GB swap memory per master

Kudu Tablet spec:

• 8 nodes
• 16GB physical memory per tablet server

Metrics says 35335258112 byte(35.34 GB) are used by generic_heap_size.

Does anyone knows about this?
