Description:
Maximum path for datafile in CREATE TABLESPACE cannot be more than 167 bytes. Error is "1502: Failed to create DATAFILE"
To reproduce run the test case below. It works only if number in repeat('a', 160) statment is less than 149.

 eval CREATE LOGFILE GROUP lg1
 ADD UNDOFILE './var/undofile.dat'
 INITIAL_SIZE 16M
 UNDO_BUFFER_SIZE = 1M
 ENGINE=NDB;

let $path2 = `SELECT CONCAT('./var/', repeat('a', 160), '/datafile.dat')`;

 eval CREATE TABLESPACE ts1
 ADD DATAFILE '$path2'
 USE LOGFILE GROUP lg1
 INITIAL_SIZE 12M
 ENGINE NDB;

 eval ALTER TABLESPACE ts1
 DROP DATAFILE '$path2'
 ENGINE NDB;

 eval DROP TABLESPACE ts1 ENGINE NDB;

 eval DROP LOGFILE GROUP lg1
 ENGINE=NDB;

How to repeat:
see above

I concider this to be duplicate of bug#16471

Can you indicate here and in future cases why this is a duplicate (i.e. because the same code is determining the path/file length, etc.) 

Just that we understand things better
Thanks

ok, sure good idea.
anyway, yes
it is the exact same code handling filenames for undo/data files
