-----------------------------------
Summary: Turn off command help that follows all errors in shell
Key: HBASE-20270
URL: https://issues.apache.org/jira/browse/HBASE-20270
Project: HBase
Issue Type: Task
Components: shell
Affects Versions: 2.0.0
Reporter: Sean Busbey
Fix For: 2.0.0
Right now if a shell command gives an error, any error, it then echos the
command help. It makes it harder to see the actual error text and is annoying.
example:
{code}
hbase(main):007:0> create 'test:a_table', 'family', { NUMREGIONS => 20,
SPLITALGO => 'HexStringSplit'}
ERROR: Unknown namespace test!
Creates a table. Pass a table name, and a set of column family
specifications (at least one), and, optionally, table configuration.
Column specification can be a simple string (name), or a dictionary
(dictionaries are described below in main help output), necessarily
including NAME attribute.
Examples:
Create a table with namespace=ns1 and table qualifier=t1
hbase> create 'ns1:t1', {NAME => 'f1', VERSIONS => 5}
Create a table with namespace=default and table qualifier=t1
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', {NAME => 'f1', CONFIGURATION =>
{'hbase.hstore.blockingStoreFiles' => '10'}}
hbase> create 't1', {NAME => 'f1', IS_MOB => true, MOB_THRESHOLD => 1000000,
MOB_COMPACT_PARTITION_POLICY => 'weekly'}
Table configuration options can be put at the end.
Examples:
hbase> create 'ns1:t1', 'f1', SPLITS => ['10', '20', '30', '40']
hbase> create 't1', 'f1', SPLITS => ['10', '20', '30', '40']
hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt', OWNER => 'johndoe'
hbase> create 't1', {NAME => 'f1', VERSIONS => 5}, METADATA => { 'mykey' =>
'myvalue' }
hbase> # Optionally pre-split the table into NUMREGIONS, using
hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'}
hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit',
REGION_REPLICATION => 2, CONFIGURATION =>
{'hbase.hregion.scan.loadColumnFamiliesOnDemand' => 'true'}}
hbase> create 't1', {NAME => 'f1', DFS_REPLICATION => 1}
You can also keep around a reference to the created table:
hbase> t1 = create 't1', 'f1'
Which gives you a reference to the table named 't1', on which you can then
call methods.
Took 0.0221 seconds
hbase(main):008:0> create_namespace 'test'
Took 0.2554 seconds
hbase(main):009:0> create 'test:a_table', 'family', { NUMREGIONS => 20,
SPLITALGO => 'HexStringSplit'}
Created table test:a_table
Took 1.2264 seconds
{code}
I was trying to make a table in the test namespace before making the namespace.
Much faster to recognize and move on when the error text isn't followed by 80x
the text.
