Looking at the Hadoop code gives no direct clue (to me), but it does seem
to indicate that you are not using the 2.7.2 version, which might explain the
inconsistent results. Maybe your local maven repo has the wrong version?
The stack trace ends with:
Caused by: java.io.IOException: Mkdirs failed to create
/usr/src/tinkerpop/spark-gremlin/target/test-case-data/SparkHadoopGraphProvider/graph-provider-data/~reducing/_temporary/0/_temporary/attempt_201611051613_15726_r_000000_0
(exists=false, cwd=file:/usr/src/tinkerpop/spark-gremlin)
at
org.apache.hadoop.fs.ChecksumFileSystem.create(ChecksumFileSystem.java:450)

org.apache.hadoop.fs.ChecksumFileSystem.create(ChecksumFileSystem.java:435)
I grabbed the related source from for version 2.7.2 from here:
https://archive.apache.org/dist/hadoop/core/hadoop-2.7.2/
https://archive.apache.org/dist/hadoop/core/hadoop-2.7.2/hadoop-2.7.2-src.tar.gz
hadoop-2.7.2-src/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/ChecksumFileSystem.java
The related code does have a call to create() on line 435 but the exception
is thrown on line 449:
@Override
public FSDataOutputStream create(Path f, FsPermission permission,
boolean overwrite, int bufferSize, short replication, long blockSize,
Progressable progress) throws IOException {
return create(f, permission, overwrite, true, bufferSize, // 435
replication, blockSize, progress);
}
private FSDataOutputStream create(Path f, FsPermission permission,
boolean overwrite, boolean createParent, int bufferSize,
short replication, long blockSize,
Progressable progress) throws IOException {
Path parent = f.getParent();
if (parent != null) {
if (!createParent && !exists(parent)) {
throw new FileNotFoundException("Parent directory doesn't exist: "
+ parent);
} else if (!mkdirs(parent)) {
throw new IOException("Mkdirs failed to create " + parent //449
+ " (exists=" + exists(parent) + ", cwd=" +
getWorkingDirectory() // 450
+ ")");
}
}
