Line 121 in HbaseLoadCacheStore.java is rs=hbaseBean.hTable.get(new
Get(Bytes.toBytes(key)));
In addition, that ket is neither existed in ignite cache nor in hbase.
Thanks for your help.

Hi,
When I use readthrough to get a key neither existed in ignite cache nor in
hbase, console shows nullpointerexception.
Is it nessary for hbase to have the record? In addition to this way,how can I
avoid that exception?
