Java CloseRegionResponse.getClosed方法代码示例

/**
 * For expert-admins. Runs close on the regionserver. Closes a region based on
 * the encoded region name. The region server name is mandatory. If the
 * servername is provided then based on the online regions in the specified
 * regionserver the specified region will be closed. The master will not be
 * informed of the close. Note that the regionname is the encoded regionname.
 *
 * @param encodedRegionName
 *          The encoded region name; i.e. the hash that makes up the region
 *          name suffix: e.g. if regionname is
 *          <code>TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396.</code>

 *          <code>527db22f95c8a9e0116f0cc13c680396</code>.
 * @param serverName
 *          The servername of the regionserver. A server name is made of host,
 *          port and startcode. This is mandatory. Here is an example:
 *          <code> host187.example.com,60020,1289493121758</code>
 * @return true if the region was closed, false if not.
 * @throws IOException
 *           if a remote or network exception occurs
