             Summary: Reading from HDFS after ctrl+c(SIGTERM) causes python hangs
                 Key: ARROW-7038
                 URL: https://issues.apache.org/jira/browse/ARROW-7038
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
         Environment: RHEL 7.4
python 3.6.7
pyarrow 0.11.1
hadoop 2.7.2
            Reporter: Kevin Jung


Python always hangs when it reads the parquet file from hdfs twice after sending ctrl+c.

To reproduce,
{code:java}
import pyarrow.parquet as pq
pq.read_table('hdfs://localhost:9000/path/to/parquet')
# Ctrl+C here
pq.read_table('hdfs://localhost:9000/path/to/parquet')
# hangs{code}
There's the weird thing ctrl+c at line 3 doesn't produce KeyboardInterrupt even though using the local file produces it at all.

For example,
{code:java}
import pyarrow.parquet as pq
pq.read_table('/home/brightics/t5y69ppsctftwbdg')
# doing Ctrl+C here prints out 'KeyboardInterrupt'
pq.read_table('/home/brightics/t5y69ppsctftwbdg')
# run properly{code}
Is this a sort of bug from JNI?
