[exalate-issue-sync[bot]]

Steps to reproduce :

1) Started h2o as below from latest master:

java -Xmx5g -jar -ea h2o.jar -experimental -name no

2) importFiles [ "/Users/nmadabhushi/0xdata/h2o-dev/smalldata/airlines/allyears2k.zip" ]

3) Parse 4) getFrameSummary "allyears2k.hex" 5) buildModel 'pca', {"model_id":"pca-1-82378c30-3b15-4bbb-9c39-92a6e2a31727","training_frame":"allyears2k.hex","ignored_columns":["C5","C7","C12","C14","C15","C16","C20","C21","C23","C25","C26","C27","C28","C29"],"ignore_const_cols":true,"transform":"STANDARDIZE","pca_method":"GramSVD","k":1,"max_iterations":1000,"seed":1436311869164163000,"loading_name":"PCALoading__88734f699adcd39b8c2788093ec74e7c","use_all_factor_levels":false,"score_each_iteration":false}

Neeraja Madabhushi commented: This is reproducible...

[exalate-issue-sync[bot]]

Neeraja Madabhushi commented: On h2o-2 it did complete after 1.5 hrs

Attached is screenshot on completed job.

Former user commented: I tried using the h2o-2 JAMA jar file, and it completed successfully in 22 minutes (see attached screenshot). I will run it a few more times to ensure this wasn't an intermittent failure. Stay tuned...

Former user commented: Running a test for this exact case on Jenkins to see if any errors pop up: http://172.16.2.161:8080/view/Experimental/job/h2o_master_DEV_PCA_runit_small/

Former user commented: Jenkins job on two different machines continuously passes. I'm closing this unless someone can reproduce this consistently.
