Subject Re: About the hicc start in eclipse
Date Wed, 20 Jun 2012 14:04:18 GMT
hi ,Eric:

*                 thanks. you are right ,there must be  a .xml file rather
than a directory.  and i have already set it according to your instructions
.  now     the question is that the *config.get("fs.default.name")
result *is null. Actually,
**even if **when i* manually loading  config.get("fs.default.name")*
**=hdfs://localhost:9000.
 **just only  create a  /chukwa/hicc/widgets  empty directory  *structure* on
the hdfs ,and did not upload the “descriptors” file to hdfs。*
*   the key is why  unable to find the jar file in the classpath of the
current。*
*   This is my chukwa-env.sh*
