The root cause of this istuation is the difference between `LocalFileSystem` and `DistributedFileSystem`. `LocalFileSystem.exists()` returns `false`, but `DistributedFileSystem.exists` raises Exception. > {code} > scala> spark.version > res0: String = 2.4.0-SNAPSHOT > scala> spark.read.json("file:///usr/hdp/current/spark-client/examples/src/main/resources/people.json").show > +----+-------+ > | age| name| > +----+-------+ > |null|Michael| > | 30| Andy| > | 19| Justin| > +----+-------+ > scala> spark.read.json("hdfs:///tmp/people.json") > 18/02/15 05:00:48 WARN streaming.FileStreamSink: Error while looking for metadata directory. > 18/02/15 05:00:48 WARN streaming.FileStreamSink: Error while looking for metadata directory. > res6: org.apache.spark.sql.DataFrame = [age: bigint, name: string] > {code} > {code} > scala> spark.version > res0: String = 2.2.1 > scala> spark.read.json("hdfs:///tmp/people.json").show > 18/02/15 05:28:02 WARN FileStreamSink: Error while looking for metadata directory. > 18/02/15 05:28:02 WARN FileStreamSink: Error while looking for metadata directory. > {code} > {code} > scala> spark.version > res0: String = 2.1.2 > scala> spark.read.json("hdfs:///tmp/people.json").show > 18/02/15 05:29:53 WARN DataSource: Error while looking for metadata directory. > +----+-------+ > | age| name| > +----+-------+ > |null|Michael| > | 30| Andy| > | 19| Justin| > +----+-------+ > {code} > {code} > scala> spark.version > res0: String = 2.0.2 > scala> spark.read.json("hdfs:///tmp/people.json").show > 18/02/15 05:25:24 WARN DataSource: Error while looking for metadata directory. > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscribe@spark.apache.org For additional commands, e-mail: issues-help@spark.apache.org
