I merge issue HBASE-3744 to 0.90.2 and test it.
Find that Creating table fails when region server shutdown

Does it need try to one more times for putting Meta data?

public static void addRegionToMeta(CatalogTracker catalogTracker,
HRegionInfo regionInfo)
throws IOException {
Put put = new Put(regionInfo.getRegionName());
put.add(HConstants.CATALOG_FAMILY, HConstants.REGIONINFO_QUALIFIER,
Writables.getBytes(regionInfo));
catalogTracker.waitForMetaServerConnectionDefault().put( // try again ?
CatalogTracker.META_REGION, put);
LOG.info("Added region " + regionInfo.getRegionNameAsString() + " to META");
}

    Can you give more detail as to how many region servers were shutting down ?

    In client code Put data into Region server has one more times:
    eg:
    public void processBatch(List<Row> list,
    ....
    for (int tries = 0; tries < numRetries && retry; ++tries) { // if put data failed and try to do.
    ...

    In function addRegionToMeta. Does it need to do this ?

    catalogTracker.waitForMetaServerConnectionDefault().put( // does need try again ? It fails for checkOpen because of Region server is shutdowned.

    hmaster logs show "org.apache.hadoop.hbase.regionserver.HRegionServer.checkOpen(HRegionServer.java:2335)"

    waitForMetaServerConnectionDefault() calls waitForMeta() which should have
    waited for "hbase.master.catalog.timeout"
    What's the value for "hbase.master.catalog.timeout" on your cluster ?

    Thank you for your reply.

    I don't change it. It is default.
    But I think it is not the case the meta table doesn't assigned.
    It had got it and been putting some data into meta table,

    org.apache.hadoop.ipc.RemoteException: java.io.IOException: Server not running at org.apache.hadoop.hbase.regionserver.HRegionServer.checkOpen(HRegionServer.java:2335)

    // I mean that the exception of put function is not caught and processed.
    Does it need to do ?

    Find that Creating table fails when region server shutdown

    Does it need try to one more times for putting Meta data?

    public static void addRegionToMeta(CatalogTracker catalogTracker,
    HRegionInfo regionInfo)
    throws IOException {
    Put put = new Put(regionInfo.getRegionName());
    put.add(HConstants.CATALOG_FAMILY, HConstants.REGIONINFO_QUALIFIER,
    Writables.getBytes(regionInfo));
    catalogTracker.waitForMetaServerConnectionDefault().put(
    // try again ?
    CatalogTracker.META_REGION, put);
    LOG.info("Added region " + regionInfo.getRegionNameAsString() + " to
    META");
    }

    Thank you for your reply.

    I don't change it. It is default.
    But I think it is not the case the meta table doesn't assigned.
    It had got it and been putting some data into meta table,

    org.apache.hadoop.ipc.RemoteException: java.io.IOException: Server not running at org.apache.hadoop.hbase.regionserver.HRegionServer.checkOpen(HRegionServer.java:2335)

    // I mean that the exception of put function is not caught and processed.
    Does it need to do ?

    In client code Put data into Region server has one more times:
    eg:
    public void processBatch(List<Row> list,

    1/About classs MetaEditor. We should add a parameter:
    private volatile Configuration configuration;

    It cans get some client configure and use to

    for (int tries = 0; tries < numRetries && retry; ++tries) {
    catalogTracker.waitForMetaServerConnectionDefault().put(
    CatalogTracker.META_REGION, put);
    }

    2/Or createTable function may be modified:
    int numRetries = conf.getInt("hbase.client.retries.number", 10);

    // 3. Insert into META
    for (int tries = 0; tries < numRetries; tries++) {
    try {
    MetaEditor.addRegionToMeta(catalogTracker, region.getRegionInfo());
    }
    catch (IOException e)
    {
    LOG.warn("Insert meta failed", e);
    }
    }
