Duo Zhang updated HBASE-20691: ------------------------------ Priority: Blocker (was: Minor) > Storage policy should allow deferring to HDFS > --------------------------------------------- > > Key: HBASE-20691 > URL: https://issues.apache.org/jira/browse/HBASE-20691 > Project: HBase > Issue Type: Bug > Components: Filesystem Integration, wal > Affects Versions: 1.5.0, 2.0.0 > Reporter: Sean Busbey > Assignee: Yu Li > Priority: Blocker > Fix For: 2.1.0, 1.5.0 > > Attachments: HBASE-20691.patch, HBASE-20691.v2.patch, > HBASE-20691.v3.patch, HBASE-20691.v4.patch, HBASE-20691.v5.patch, > HBASE-20691.v6.patch, HBASE-20691.v7.patch > > > In HBase 1.1 - 1.4 we can defer storage policy decisions to HDFS by using > "NONE" as the storage policy in hbase configs. > As described on this [dev@hbase thread "WAL storage policies and interactions > with Hadoop admin > tools."|https://lists.apache.org/thread.html/d220726fab4bb4c9e117ecc8f44246402dd97bfc986a57eb22311117@%3Cdev.hbase.apache.org%3E] > we no longer have that option in 2.0.0 and 1.5.0 (as the branch is now). > Additionally, we can't set the policy to HOT in the event that HDFS has > changed the policy for a parent directory of our WALs. > We should put back that ability. Presuming this is done by re-adopting the > "NONE" placeholder variable, we need to ensure that value doesn't get passed > to HDFS APIs. Since it isn't a valid storage policy attempting to use it will > cause a bunch of logging churn (which will be a regression of the problem > HBASE-18118 sought to fix). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
