Refactor to Server Manager
--------------------------
Key: HBASE-1422
URL: https://issues.apache.org/jira/browse/HBASE-1422
Project: Hadoop HBase
Issue Type: Sub-task
Affects Versions: 0.19.2
Reporter: Evgeny Ryabitskiy
Assignee: Evgeny Ryabitskiy
Priority: Blocker
Fix For: 0.20.0
This is refactor to Server Manager class from HBASE-1017
I separate it for reasons:
* Its better to have several small patchs and apply them iterativly then one
great path
* I fu..** tired from synchronising w/ SVN (this class changes frequently),
you can saw 10 patches in HBASE-1017
We need this refactoing for reasons:
* Server Manager looks like shi**.. bad thing...
* is every time harder to make any chnages
* it is becoming more ugly every time........
What changes are done:
ServerManager has mapping:
* serverName 2 serverInfo,
* serverAddr 2 serverInfo,
* serverName 2 load,
* load 2 severName
1) serverName 2 load - not necessary if you have serverName 2 serverInfo
2) All mappings are encapsulated in ServersInfo class (inner class of
ServerManager)
3) ServersInfo has operations for adding, updating and removing information of
HRS
+ some code in RegionServer is puted in synchronised block... cause it is
working with synchronised map...
Note: this task is to make code much much more clear.. and it's not going to
change logic, so no much problem is going appear
