Tasks to perform after region open to complete deploy of region on regionserver

Parameters:

r - Region to open.

ct - Instance of CatalogTracker

daughter - True if this is daughter of a split

Throws:

org.apache.zookeeper.KeeperException

java.io.IOException

getRpcMetrics

HBaseRpcMetrics getRpcMetrics()

Returns a reference to the RPC server metrics.

addToOnlineRegions

void addToOnlineRegions(HRegion r)

Add to online regions.

Parameters:

r -

removeFromOnlineRegions

boolean removeFromOnlineRegions(java.lang.String encodedRegionName)

This method removes HRegion corresponding to hri from the Map of onlineRegions.

Parameters:

encodedRegionName -

Returns:

True if we removed a region from online list.

getFromOnlineRegions

HRegion getFromOnlineRegions(java.lang.String encodedRegionName)

Return HRegion instance. Only works if caller is in same context, in same JVM. HRegion is not serializable.

Parameters:

encodedRegionName -
