why testCliDriver_udaf_percentile_approx_23 failed?

Hi Everyone

I noticed TestCliDriver.testCliDriver_udaf_percentile_approx_23 failed
several times recently because of assert failed

Running: diff -a
/home/hiveptest/54.205.70.242-hiveptest-2/apache-svn-trunk-source/itests/qtest/../../itests/qtest/target/qfile-results/clientpositive/udaf_percentile_approx_23.q.out
/home/hiveptest/54.205.70.242-hiveptest-2/apache-svn-trunk-source/itests/qtest/../../ql/src/test/results/clientpositive/udaf_percentile_approx_23.q.out

< 342.0

I run test locally - it passed

Do you know why line 567 has different value if run on Jenkins host?
