To repeat the problem:
- Compile MariaDB with ColumnStore with a non-default -DCMAKE_INSTALL_PREFIX
- Do "make install"
- Do all necessary post-installation steps and start MariaDB/ColumnStore
- Run this SQL script:
DROP TABLE IF EXISTS t1,t2;
|
CREATE TABLE t1 (a INT) ENGINE=ColumnStore;
|
INSERT INTO t1 VALUES (1);
|
CREATE TABLE t2 (a INT) ENGINE=ColumnStore;
|
INSERT INTO t2 SELECT * FROM t1;
|
The problem happens because of this code in writeengine/splitter/we_cmdargs.cpp:
if (argc > 0)
|
fPrgmName = "cpimport.bin"; //argv[0] is splitter but we need cpimport
|
so later this call fails:
int aRet = execvp(Cmds[0], &Cmds[0]);
|
This message is added to /var/log/mariadb/columnstore/err.log:
Nov 27 17:29:44 home writeengineserver[150739]: 44.235562 |0|0|0| E 32 CAL0000: 7571 : execv error: cpimport.bin invocation failed; (errno-9); No such file or directory; Check file and try
|
The solution is to add full patch when constructing the cpimport command line:
diff --git a/writeengine/splitter/we_cmdargs.cpp b/writeengine/splitter/we_cmdargs.cpp
