Subject [jira] [Commented] (HBASE-11052) Sending random data crashes thrift service
Date Wed, 23 Apr 2014 23:44:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11052?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13979099#comment-13979099

Andrew Purtell commented on HBASE-11052:
----------------------------------------

Looks good to me. 

For 0.98 and 0.96 we could keep the default in the code for hbase.regionserver.thrift.compact
and hbase.regionserver.thrift.framed as 'false' but add entries to hbase-default.xml for these
as 'true' with a note in the description that changing it back to the old default exposes
the service to DoS.

>          Components: Thrift
>    Affects Versions: 0.98.1, 1.0.0, 0.94.18
>            Reporter: Adrian Muraru

> Upstream thrift library has a know issue (THRIFT-601) causing the thrift server to crash
with an Out-of-Memory Error when bogus requests are sent.
> This reproduces when a very large request size is sent in the request header, making
the thrift server to allocate a large memory segment leading to OOM.
> LoadBalancer health checks are the first "candidate" for bogus requests
> Thrift developers admit this is a known issue with TBinaryProtocol and their recommandation
is to use TCompactProtocol/TFramedTransport but this requires all thrift clients to be updated
(might not be feasible atm)
> So we need a fix similar to CASSANDRA-475.
