             Summary: Arrow plasma throws ArrowIOError: Encountered unexpected EOF
                 Key: ARROW-2956
                 URL: https://issues.apache.org/jira/browse/ARROW-2956
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
            Reporter: He Kaisheng


hello,

We start a plasma store with 100k memory. when storage is full, it throws ArrowIOError, not the expected PlasmaStoreFull error.

code:
{code:java}
import pyarrow.plasma as plasma
import numpy as np

plasma_client = plasma.connect(plasma_socket, '', 0)
ref = []
for _ in range(1000):
    obj_id = plasma_client.put(np.random.randint(100, size=(100, 100),
                                                      dtype=np.int16))
    data = plasma_client.get(obj_id)
    ref.append(data)
{code}
error:
{noformat}
---------------------------------------------------------------------------
ArrowIOError                              Traceback (most recent call last)
<ipython-input-2-07ec7f6f4b82> in <module>()
      2 ref = []
      3 for _ in range(1000):
----> 4     obj_id = plasma_client.put(np.random.randint(100, size=(100, 100), dtype=np.int16))
      5     data = plasma_client.get(obj_id)
      6     ref.append(data)

ArrowIOError: Encountered unexpected EOF{noformat}
this problem doesn't exist when dtype is np.int64 or share memory is larger(like more than 100M), it seems so strange, anybody knows the reason? Thanks a lot.
