@Abdel, Yes problem is similar. By the way, the jira issue allready exists isnt'it ? https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwjUscyr7tTKAhXBVhoKHf0CAjYQFggpMAE&url=http%3A%2F%2Fmail-archives.apache.org%2Fmod_mbox%2Fdrill-dev%2F201505.mbox%2F%253CJIRA.12832322.1432356299000.15684.1432356317225%40Atlassian.JIRA%253E&usg=AFQjCNHEwAdEpCBmS1QeuLhdfL8SIdTx6Q&sig2=4EM_xXq2QWd8kmC3LT2-Wg If not, I would be glad to add one. Just tell me why
@Ted, If you have new lines in your files then the files becomes unsuitable for splitting. This means that the only parallelism available in a ctas statement is multiple files Does it means newlines are incompatible with drill's distributed calculus ? Do you have a fair number of files? I have one 30GB csv file. I don't know how many parquet file it could create as process crashes because of newlines. I can imagine approx 5 parquet files 500 MB.
