Appy created HBASE-14865: ---------------------------- Summary: Support passing multiple QOPs to SaslClient/Server via hbase.rpc.protection Key: HBASE-14865 URL: https://issues.apache.org/jira/browse/HBASE-14865 Project: HBase Issue Type: Improvement Components: security Reporter: Appy
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
