Deprecation Notices in Apache HBase
Certain features and functionality in HBase are deprecated or removed in Cloudera Runtime 7.2.2. You must review these changes along with the information about the features in HBase that will be removed or deprecated in a future release.
Use this list to understand some of the deprecated items and incompatibilities if you are upgrading from HDP 2.x or CDH 5.x to CDP.
Known Incompatibilities when Upgrading from CDH and HDP
List of Major Changes
-
HBASE-16189 and HBASE-18945: You cannot open the Cloudera Runtime HFiles in CDH or HDP.
-
HBASE-18240: Changed the ReplicationEndpoint Interface.
- The Dynamic Jars Directory property
hbase.dynamic.jars.diris disabled by default. If you want to enable dynamic classloading, you can use thehbase.dynamic.jars.dirproperty in Cloudera Manager to change the default ${hbase.rootdir}/lib directory to some other location, preferably a location on HDFS. This property is flagged by Cloudera Manager as deprecated when you upgrade to CDP because the property is incompatible with HBase on cloud deployments. If you are using HBase with HDFS storage, you can ignore this warning, and keep using thehbase.use.dynamic.jarsfeature.
Co-processor API changes
-
HBASE-16769: Deprecated Protocol Buffers references from MasterObserver and RegionServerObserver.
-
HBASE-17312: [JDK8] Use default method for Observer Coprocessors. The interface classes of BaseMasterAndRegionObserver, BaseMasterObserver, BaseRegionObserver, BaseRegionServerObserver and BaseWALObserver uses JDK8’s 'default' keyword to provide empty and no-op implementations.
-

compact(ByteBuffer) createTable(ByteBuffer, List<ColumnDescriptor>) deleteTable(ByteBuffer) disableTable(ByteBuffer) enableTable(ByteBuffer) getTableNames() majorCompact(ByteBuffer) -
REST usage of Admin API:
hbase-rest org.apache.hadoop.hbase.rest RootResource getTableList() TableName[] tableNames = servlet.getAdmin().listTableNames(); SchemaResource delete(UriInfo) Admin admin = servlet.getAdmin(); update(TableSchemaModel, boolean, UriInfo) Admin admin = servlet.getAdmin(); StorageClusterStatusResource get(UriInfo) ClusterStatus status = servlet.getAdmin().getClusterStatus(); StorageClusterVersionResource get(UriInfo) model.setVersion(servlet.getAdmin().getClusterStatus().getHBaseVersion()); TableResource exists() return servlet.getAdmin().tableExists(TableName.valueOf(table));
