Class Summary
Chore Chore is a task performed on a period in hbase.
HBaseConfiguration Adds HBase configuration files to a Configuration
HColumnDescriptor An HColumnDescriptor contains information about a column family such as the number of versions, compression settings, etc.
HMsg HMsg is for communicating instructions between the HMaster and the HRegionServers.
HRegionInfo HRegion information.
HRegionLocation Contains the HRegionInfo for the region and the HServerAddress for the HRegionServer serving the region
HServerAddress HServerAddress is a "label" for a HBase server that combines the host name and port number.
HServerInfo HServerInfo contains metainfo about an HRegionServer, Currently it only contains the server start code.
HServerLoad This class encapsulates metrics for determining the load on a HRegionServer
HServerLoad.RegionLoad Encapsulates per-region loading metrics.
HStoreKey A Key for a stored row.
HStoreKey.BeforeThisStoreKey Pass this class into MapFile.getClosest when searching for the key that comes BEFORE this one but NOT this one.
HStoreKey.HStoreKeyWritableComparator Passed as comparator for memcache and for store files.
HTableDescriptor HTableDescriptor contains the name of an HTable, and its column families.
Leases Leases There are several server classes in HBase that need to track external clients that occasionally send heartbeats.
LocalHBaseCluster This class creates a single process HBase cluster.
LocalHBaseCluster.RegionServerThread runs region servers
RegionHistorian The Region Historian task is to keep track of every modification a region has to go through.
RemoteExceptionHandler An immutable class which contains a static method for handling org.apache.hadoop.ipc.RemoteException exceptions.
