Hello dear.
My name is Joseph Hwang. I am a developer in South Korea.
I try to develop hadoop file system client application with pyarrow 3 on
windows 10. First, my development environment are like below,
OS : Windows 10
Language : Anaconda 2020.11
IDE : eclipse
And my environment variables are
JAVA_HOME : C:\Program Files\Java\jdk-11.0.10
HADOOP_HOME : C:\hadoop-3.3.0
ARROW_LIBHDFS_DIR : C:\hadoop-3.3.0\lib\native
CLASSPATH = 'hdfs classpath --glob'
These are my short python codes with pyarrow
from pyarrow import fs
hdfs = fs.HadoopFileSystem('localhost', port=9000)
But I can not connect to my hadoop file system. The brought error is
hdfs = fs.HadoopFileSystem('localhost', port=9000)
File "pyarrow\_hdfs.pyx", line 83, in pyarrow._hdfs.HadoopFileSystem.__init__
File "pyarrow\error.pxi", line 122, in
pyarrow.lib.pyarrow_internal_check_status
File "pyarrow\error.pxi", line 99, in pyarrow.lib.check_status
OSError: Unable to load libjvm:
I think my codes have some problems with java configuration but I have no idea
how to correct this error.
Kindly inform me of your advise to correct this error. Thank you for reading my
e-mail.
Best regards.
