Hi all, After do some tests,finally I solve it.I wrote here for other people who met this question. here's a example of data format error I faced 0 0:0 1:0 2:1 1 1:1 3:2 the data for 0:0 and 1:0/1:1 is the reason for ArrayIndexOutOfBoundsException.If someone who faced the same question just delete them from u past data or update it. Since it was worked in libsvm-tools,so I guess in spark MLlib it just implements a bit different.
