actually, I found even when I try to create this table, it also failed with
it already exist! What does HBase check to see if a table already exist? I
did scan .META. , which also does not show this table.
hbase(main):009:0> list
TABLE
tsdb-uid
1 row(s) in 0.0100 seconds
hbase(main):010:0> create 'tsdb', {NAME => 't', BLOOMFILTER => 'ROW',
REPLICATION_SCOPE => '1', VERSIONS => '1', COMPRESSION => 'SNAPPY'}
ERROR: Table already exists: tsdb!
Here is some help for this command:
Create table; pass table name, a dictionary of specifications per
column family, and optionally a dictionary of table configuration.
Dictionaries are described below in the GENERAL NOTES section.
Examples:
hbase> create 't1', {NAME => 'f1', VERSIONS => 5}
hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
hbase> # The above in shorthand would be the following:
hbase> create 't1', 'f1', 'f2', 'f3'
hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000,
BLOCKCACHE => true}
hbase> create 't1', 'f1', {SPLITS => ['10', '20', '30', '40']}
hbase> create 't1', 'f1', {SPLITS_FILE => 'splits.txt'}
hbase> # Optionally pre-split the table into NUMREGIONS, using
hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO =>
'HexStringSplit'}
