Which hadoop release are you using ?

Can you pastebin more of the server logs ?


bq. load file larger than 20M


Do you store such file(s) directly on hdfs and put its path in hbase ?

See HBASE-11339 HBase MOB

when hbase stores pics or file  under 200k, it works well, 

but if you load file larger than 20M , hbase definitely down!


what's wrong with it ? 

can anyone help use?
