Brett Randall created HDFS-5478: ----------------------------------- Summary: File size reports as zero after writing and calling FSDataOutputStream#hsync() Key: HDFS-5478 URL: https://issues.apache.org/jira/browse/HDFS-5478 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.0.0-alpha Environment: RHEL/OEL 6u3 Reporter: Brett Randall
Using a Java client to write to a FSDataOutputStream. After some data is written and hsync() is called, {{hdfs dfs -get /path/to/file}} gets a file containing the data written so-far, all good. {{hdfs dfs -ls /path/to/file}} however reports a zero-byte file, presumably until the stream is closed (it then shows the correct size). Hue File Browser (running CDH4) also shows zero bytes until the stream is closed. See also http://grokbase.com/t/hadoop/hdfs-user/113j63nrce/zero-file-size-after-hsync which discusses the same problem. After the buffer is flushed it would be good if the reported file size was updated. -- This message was sent by Atlassian JIRA (v6.1#6144)
