Zhong Yanghong commented on KYLIN-2846:
---------------------------------------
There's two issues currently found.
* In HBase, htable data with different namespace are organized with different
HDFS folders. Since hdfs files are case-sensitive, the namespace & table name
should be case-sensitive. In {{CubeHTableUtil}} for htable creation,
{code}
HTableDescriptor tableDesc = new
HTableDescriptor(TableName.valueOf(cubeSegment.getStorageLocationIdentifier()));
{code}
it's not inconsistent with
{code}
HTable htable = new HTable(hbaseConf,
getOptionValue(OPTION_HTABLE_NAME).toUpperCase());
{code}
in {{CubeHFileJob}}
* After add namespace for {{storageLocationIdentifier}} of {{CubeSegment}}, it
should also be considered in {{StorageCleanJobHbaseUtil}}. Otherwise, when
using this tool to delete useless htables, simple string match filter will not
run correctly.
> Add a config of hbase namespace for cube storage
