Subject RE: hbase use error
Date Wed, 17 Sep 2014 02:47:30 GMT
thank you for your reply so quickly.we cdh 5.store files directly in hbase , not path.
i have read some hbase schema design , says that it is recommended that for large file store
path in hbase , and put real content in hdfs sequencefile. but i think 20M is not to big.
i download those log now , and send you later.
where can i find  HBASE-11339 HBase MOB?

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

hello ,everyone        i use hbase to store small pic or files , and meet an exception raised

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? 

URGENT!!!
