kudu leader master memory leak

[#1]

Hello guys.

I'm trying to use kudu as my data store.

But my kudu leader master keep dead by OOM.

Follower masters and all tablet uses very few memory.

Leader master's memory usage

Follower master's memory usage

Tablet Server's memory usage

Kudu Master spec is:

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

Kudu Tablet spec is:

• 8 tablet servers
• 16GB physical memory per tablet server

Metrics says generic_heap_size is 35335258112(35335 MB, 35.34 GB).

I tried to debug memory usage, but pprof don't catch all memories.

(pprof shows only 2063 MB)

Does anyone know reason?
