[jira] [Commented] (PHOENIX-4719) Avoid static initialization deadlock while loading regions

["Pedro Boado (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-4719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16459313#comment-16459313 ] 

Pedro Boado commented on PHOENIX-4719:
--------------------------------------






RS reaches a static initialization deadlock between  org.apache.phoenix.exception.SQLExceptionCode  and org.apache.phoenix.jdbc.PhoenixDatabaseMetaData.

SQLException:246  uses a static member of PhoenixDatabaseMetadata . And  PhoenixDatabaseMetadata:93  ( static field ) ends up accesing a static field from SQLException  when building  TableProperty:237

In the process this ends up also blocking ServerUtil:73 and indirectly DelegateRegionCoprocessorEnvironment:50 .

> HBase cluster initialization appears to fail as RS is not able to serve all table regions. 
> Almost all table regions are stuck in transition waiting for the first three regions to be opened. After a while the process times out and RS fails.
