3 spark slaves Reporter: Bihui Jin Firstly I saved a spark dataframe to local disk in spark cluster mode with " df.write \ .format('json') \ .save('file:///root/bughunter/', mode='overwrite') " (using interface provide by {color:#FF0000}pyspark{color}) Then I load it with " spark.read.format('json').load('file:///root/bughunter/') " But it faild with " org.apache.spark.sql.AnalysisException: Unable to infer schema for JSON. It must be specified manually." And I check every node's disk: In master: only the file named "_SUCCESS" exists in /root/bughunter/; In each slave, there is a folder named "_temporary" exists in /root/bughunter/ -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
