Suspected memory leak

In HBaseClient proceess, I found heap has been increased.
I used command 'cat smaps' to get the heap size.
It seems in case when the threads pool in HTable has released the no using thread, if you use putlist api to put data again, the memory is increased.
Who has experience in this case?

Below is the heap of Hbase client:
C3S31:/proc/18769 # cat smaps
