Examples with EventLoopGroup org.apache.hbase.thirdparty.io.netty.channel.EventLoopGroup used on opensource projects

Example 1 with EventLoopGroup

use of org.apache.hbase.thirdparty.io.netty.channel.EventLoopGroup in project hbase by apache.

the class AsyncFSWALProvider method createAsyncWriter.

/**
 * Public because of AsyncFSWAL. Should be package-private
 */
public static AsyncWriter createAsyncWriter(Configuration conf, FileSystem fs, Path path, boolean overwritable, long blocksize, EventLoopGroup eventLoopGroup, Class<? extends Channel> channelClass, StreamSlowMonitor monitor) throws IOException {
    // Configuration already does caching for the Class lookup.
    Class<? extends AsyncWriter> logWriterClass = conf.getClass(WRITER_IMPL, AsyncProtobufLogWriter.class, AsyncWriter.class);
    try {
        AsyncWriter writer = logWriterClass.getConstructor(EventLoopGroup.class, Class.class).newInstance(eventLoopGroup, channelClass);
        writer.init(fs, path, conf, overwritable, blocksize, monitor);
        return writer;
    } catch (Exception e) {
        if (e instanceof CommonFSUtils.StreamLacksCapabilityException) {
            LOG.error("The RegionServer async write ahead log provider " + "relies on the ability to call " + e.getMessage() + " for proper operation during " + "component failures, but the current FileSystem does not support doing so. Please " + "check the config value of '" + CommonFSUtils.HBASE_WAL_DIR + "' and ensure " + "it points to a FileSystem mount that has suitable capabilities for output streams.");
        } else {
            LOG.debug("Error instantiating log writer.", e);
        }
        Throwables.propagateIfPossible(e, IOException.class);
        throw new IOException("cannot get log writer", e);
    }
}

Example 2 with EventLoopGroup

use of org.apache.hbase.thirdparty.io.netty.channel.EventLoopGroup in project hbase by apache.

the class NettyRpcClientConfigHelper method getDefaultEventLoopConfig.

private static Pair<EventLoopGroup, Class<? extends Channel>> getDefaultEventLoopConfig(Configuration conf) {
    Pair<EventLoopGroup, Class<? extends Channel>> eventLoop = DEFAULT_EVENT_LOOP;
    if (eventLoop != null) {
        return eventLoop;
    }
    synchronized (NettyRpcClientConfigHelper.class) {
        eventLoop = DEFAULT_EVENT_LOOP;
        if (eventLoop != null) {
            return eventLoop;
        }
        int threadCount = conf.getInt(HBASE_NETTY_EVENTLOOP_RPCCLIENT_THREADCOUNT_KEY, 0);
        eventLoop = new Pair<>(new NioEventLoopGroup(threadCount, new DefaultThreadFactory("RPCClient-NioEventLoopGroup", true, Thread.NORM_PRIORITY)), NioSocketChannel.class);
        DEFAULT_EVENT_LOOP = eventLoop;
    }
    return eventLoop;
