".... | Percentage of io.serverThreads used by netty to process ChunkFetchRequest.
Shuffle server will use a separate EventLoopGroup to process ChunkFetchRequest messages.
Although when calling the async writeAndFlush on the underlying channel to send
response back to client, the I/O on the channel is still being handled by
{@link org.apache.spark.network.server.TransportServer}'s default EventLoopGroup
that's registered with the Channel, by waiting inside the ChunkFetchRequest handler
threads for the completion of sending back responses, we are able to put a limit on
the max number of threads from TransportServer's default EventLoopGroup that are
going to be consumed by writing response to ChunkFetchRequest, which are I/O intensive
and could take long time to process due to disk contentions. By configuring a slightly
higher number of shuffler server threads, we are able to reserve some threads for
handling other RPC messages, thus making the Client less likely to experience timeout
when sending RPC messages to the shuffle server. The number of threads used for handling
chunked fetch requests are percentage of io.serverThreads (if defined) else it is a percentage
of 2 * #cores. However, a percentage of 0 means netty default number of threads which
is 2 * #cores ignoring io.serverThreads. The percentage here is configured via
spark.shuffle.server.chunkFetchHandlerThreadsPercent. The returned value is rounded off to
ceiling of the nearest integer. | [

have the same permissions as the current thread.
<p>
This factory creates threads with the same settings as {@link
Executors#defaultThreadFactory}, additionally setting the
AccessControlContext and contextClassLoader of new threads to
be the same as the thread invoking this
{@code privilegedThreadFactory} method. A new
{@code privilegedThreadFactory} can be created within an
{@link java.security.AccessController#doPrivileged AccessController.doPrivileged}
action setting the current thread's access control context to
create threads with the selected permission settings holding
within that action.
</p>
<p>Note that while tasks running within such threads will have
the same access control and class loader settings as the
current thread, they need not have the same {@link
java.lang.ThreadLocal} or {@link
java.lang.InheritableThreadLocal} values. If necessary,
particular values of thread locals can be set or reset before
any task runs in {@link ThreadPoolExecutor} subclasses using
{@link ThreadPoolExecutor#beforeExecute(Thread, Runnable)}.
Also, if it is necessary to initialize worker threads to have
the same InheritableThreadLocal settings as some other
designated thread, you can create a custom ThreadFactory in
which that thread waits for and services requests to create
others that will inherit its values.
@param registry the {@link MetricRegistry} that will contain the metrics.
@param name the (metrics) name for this executor service, see {@link MetricRegistry#name(String, String...)}.
@return a thread factory

context does not have permission to both get and set context

This CLI works in two different modes:
<ul>
<li>"spark-submit": if <i>class</i> is "org.apache.spark.deploy.SparkSubmit", the
{@link SparkLauncher} class is used to launch a Spark application.</li>
<li>"spark-class": if another class is provided, an internal Spark class is run.</li>
</ul>
This class works in tandem with the "bin/spark-class" script on Unix-like systems, and
"bin/spark-class2.cmd" batch script on Windows to execute the final command.
<p>
On Unix-like systems, the output is a list of command arguments, separated by the NULL
character. On Windows, the output is a command line suitable for direct execution from the
script. | [
