--------------------------------------
Summary: bug of hbase option TTL
Key: TRAFODION-2868
URL: https://issues.apache.org/jira/browse/TRAFODION-2868
Project: Apache Trafodion
Issue Type: Bug
Components: sql-cmp
Affects Versions: any
Reporter: liyingshuai
create a table with TTL option, then an error occurred:
CREATE TABLE t_hbaseoption22(c1 INT NOT NULL, c2 varchar(5)) SALT USING 2
PARTITIONS ON (c1) store BY (c1) HBASE_OPTIONS (TTL='-1');
*** ERROR[8448] Unable to access Hbase interface. Call to
CmpSeabaseDDL::generateHbaseOptionsArray() returned error
HBASE_CREATE_OPTIONS_ERROR(710). Cause: TTL. [2017-12-25 17:45:01]
as described in SQL REFERENCE MANUAL that the accepted value of TTL can be
'-1' (forever) and 'positive-integer'
i found the following source code, if the value is -1 then throw an error
and TTL in hbase source code -1 means forever:
CmpSeabaseDDLcommon.cpp
// 代码中设置不能等于-1
else if ((hbaseOption->key() == "TIME_TO_LIVE") || (hbaseOption->key() ==
"TTL"))
{
if ((str_atoi(hbaseOption->val().data(),
hbaseOption->val().length()) == -1) ||
(!hbaseCreateOptionsArray[HBASE_TTL].empty()))
isError = TRUE;
hbaseCreateOptionsArray[HBASE_TTL] = hbaseOption->val();
