Subject [jira] [Updated] (HBASE-14865) Support passing multiple QOPs to SaslClient/Server via hbase.rpc.protection
Date Tue, 24 Nov 2015 00:49:11 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14865?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Appy updated HBASE-14865:
-------------------------
    Attachment: HBASE-14865-master-v2.patch

Fixes AsyncSecureIPC test.
Test was timing out because async had this bug to retry infinite times if kerberos is enabled
and test was configured to timeout in 5 seconds. So even though the expected exception was
happening, it'll keep retrying and timeout. :-/

> Currently, we can set the value of hbase.rpc.protection to one of authentication/integrity/privacy.
It is the used to set {{javax.security.sasl.qop}} in SaslUtil.java.
> The problem is, if a cluster wants to switch from one qop to another, it'll have to take
a downtime. Rolling upgrade will create a situation where some nodes have old value and some
have new, which'll prevent any communication between them. There will be similar issue when
clients will try to connect.
> {{javax.security.sasl.qop}} can take in a list of QOP in preferences order. So a transition
from qop1 to qop2 can be easily done like this
> "qop1" --> "qop2,qop1" --> rolling restart --> "qop2" --> rolling restart
> Need to change hbase.rpc.protection to accept a list too.
