Example 6 with RegionMovedException

use of org.apache.hadoop.hbase.exceptions.RegionMovedException in project hbase by apache.

the class ServerCall method setExceptionResponse.

static void setExceptionResponse(Throwable t, String errorMsg, ResponseHeader.Builder headerBuilder) {
    ExceptionResponse.Builder exceptionBuilder = ExceptionResponse.newBuilder();
    exceptionBuilder.setExceptionClassName(t.getClass().getName());
    exceptionBuilder.setStackTrace(errorMsg);
    exceptionBuilder.setDoNotRetry(t instanceof DoNotRetryIOException);
    if (t instanceof RegionMovedException) {
        // Special casing for this exception.  This is only one carrying a payload.
        // Do this instead of build a generic system for allowing exceptions carry
        // any kind of payload.
        RegionMovedException rme = (RegionMovedException) t;
        exceptionBuilder.setHostname(rme.getHostname());
        exceptionBuilder.setPort(rme.getPort());
    }
    // Set the exception as the result of the method invocation.
    headerBuilder.setException(exceptionBuilder.build());
