This answers to my own question. Hope to help other people who may experience same problem.
It's heap space problem. My case is caused by Google Photo screen saver. Everytime the screen saver is triggered. Not long the JVM can't allocate enough heap space and post.jar failed. scott.chu，scott....@udngroup.com 2016/5/20 (週五) ----- Original Message ----- From: scott(自己) To: solr-user CC: Date: 2016/5/18 (週三) 13:37 Subject: Why error #400 bad request somtimes where I add doc to Solrcloud collection? [scottchu] I add doc by running post.jar with xml files but sometimes get error #400(Bad Request). At first, I doubt the xml files has problem but after I stop nodes and restart them. I add same doc again and it's successful. According post.jar output below, though NMLBOym_a_UN2004_07_20160511_1018.xml got error #400 but at last it commit the index change. However, it doesn't write the index successfully (I've query that id and not found). What could be the possible cause?
