> when i init pyarrow filesystem to connect hdfs clusfter in spark,the libhdfs
> throws error:
> {code:java}
> org/apache/hadoop/fs/FileSystem class not found
> {code}
> I print out the CLASSPATH, the classpath value is wildcard mode
> {code:java}
> ../share/hadoop/hdfs;spark/spark-2.0.2-bin-hadoop2.7/jars...
> {code}
> The value is set by spark,but libhdfs must load class from jar files.
>
> Root cause is:
> In hdfs.py we just check the string ''hadoop" in classpath,but not jar file
> {code:java}
> def _maybe_set_hadoop_classpath():
> if 'hadoop' in os.environ.get('CLASSPATH', ''):
> return{code}
