Hi All,
For some reason, my hdfs source code can't compile anymore. ~1-2 weeks ago it was compiling fine but now it's not. I haven't made any changes to my code since I last compiled.

When I do ant clean jar: I get the following errors.

Hi Harold,
      The error message "cannot find symbol" hints of not having necessary libraries. Looks like it is trying to access Kerberos libraries which it is unable to find. You can check if all the required Kerberos libraries are available.

Sagar

Hi,

I also have the source from hadoop-common. However, when I do ant clean jar from hdfs folder, ivy seems to try and download the hadoop-core jar file from the repository?

Maybe the newer version of hadoop-core is not compatible with mine?
How do I force the compile to use my own jar file, the jar from the version of hadoop-common that I have?
Thanks,
Harold

Hi Harold,
  It seems you don't have latest hdfs code. KerberosInfo annotation has
slightly changed in the latest code.
  Also, KerberosInfo not being found means you have older jar for common.
Try 'ant clean clean-cache'  before compiling.

To use your on version of jar do ant mvn-install in the the common
And in hdfs give -Dresolvers=internal flag to the ant command line. Please
make sure to clean-cache before this.
