Hi Liang,

Thank you for your interest. Sure we would consider you adding in
interested contributors list.

disk directly as well as GC pressure caused by caching ?

Yes.

>whether Mnemonic could solve Hadoop Namenode pressure of large
scale of cluster scenaros, or not?
Yeah, we are thinking on some aspects considering memory and GC overheads
in Namenode too.
Example couple of JIRAs already there in HDFS to move some of data
structure to off heap. So, we had plans to get the standard data
structures from this library and can make use of them push.
Also we could make advantage if persistence here.


@Yanping/Gary, may be you could add more points if you have?

Regards,
Uma
