[jira] [Created] (FLINK-3014) Return code from InputStream#read()
should be checked in PythonStreamer#sendBroadCastVariables
Ted Yu created FLINK-3014:
-----------------------------
Summary: Return code from InputStream#read() should be checked in PythonStreamer#sendBroadCastVariables
Key: FLINK-3014
URL: https://issues.apache.org/jira/browse/FLINK-3014
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
Here is related code (there're 3 occurrences in the method):
{code}
in.read(buffer, 0, 4);
checkForError();
{code}
java.io.InputStream.read(byte[], int, int) returns the number of bytes read.
The return value should be checked because checkForError() does this:
{code}
if (getInt(buffer, 0) == -2) {
try { //wait before terminating to ensure that the complete error message is printed
{code}
Incorrect result may be returned if fewer than 4 bytes of data are read.
