--------------------------------------------------------
I select the .tmp data in hive,then it cauth a error:
Failed with exception
java.io.IOException:org.apache.hadoop.hive.serde2.SerDeException:
org.codehaus.jackson.JsonParseException: Illegal character ((CTRL-CHAR, code
1)): only regular white space (\r, \n, \t) is allowed between tokens
at [Source: java.io.ByteArrayInputStream@7730ef88; line: 1, column: 2]
I think is the compressed file with '.tmp' suffix is in use and is not a
completed compressed file,so codec in hadoop colud not recognize the content of
it
After all:Yes，I use the "." prefix to skip ".tmp" file,but the flume docuent
dos not mention it...

> Currently we write to a .tmp file. The problem is that if MR jobs are being
> run on the directory we are writing to, then it's common for an MR job to
> list the directory, get a .tmp file and then in the mean time the .tmp file
> is renamed causing the job to fail when run.
> Using JavaMR you can use a PathFilter to avoid this, however a custom
> solution is required for Pig, Hive, etc.
> Perhaps we should write to a hidden file so that MR never tries to process
> data in flight.
