pom相关性：

<dependency>
        <groupId>org.apache.hive.hcatalog</groupId>
        <artifactId>hive-webhcat-java-client</artifactId>
        <version>1.2.1</version>
    </dependency>

我能够获得列、分区列、输入文件格式等。
有用代码：

HiveConf hcatConf = new HiveConf();

    hcatConf.setVar(HiveConf.ConfVars.METASTOREURIS, connectionUri);
    hcatConf.set("hive.metastore.local", "false");
    hcatConf.setIntVar(HiveConf.ConfVars.METASTORETHRIFTCONNECTIONRETRIES, THRIFT_CONNECTION_RETRY);
    hcatConf.set(HiveConf.ConfVars.HIVE_SUPPORT_CONCURRENCY.varname, "true");
    hcatConf.set(HiveConf.ConfVars.SEMANTIC_ANALYZER_HOOK.varname, HCatSemanticAnalyzer.class.getName());
    hcatConf.set(HiveConf.ConfVars.PREEXECHOOKS.varname, "");
    hcatConf.set(HiveConf.ConfVars.POSTEXECHOOKS.varname, "");

    hcatConf.setTimeVar(HiveConf.ConfVars.METASTORE_CLIENT_SOCKET_TIMEOUT, TIME_OUT, TimeUnit.MILLISECONDS);

    HCatClient client = null;
    HCatTable hTable = null;

    try {
        client = HCatClient.create(hcatConf);
        hTable = client.getTable(databaseName, tableName);
        System.out.println(hTable.getInputFileFormat());
        System.out.println(hTable.getOutputFileFormat());
        System.out.println(hTable.getSerdeLib());

    } catch (HCatException hCatEx) {
        LOG.error("Not able to connect to hive. Caused By;", hCatEx);
    }

如何获取文本表的行和字段分隔符？
根据getserdeparams（）的javadoc， public Map<String,String> getSerdeParams() -返回字段分隔符等参数。
但就我而言，这张Map上只有一个条目

{serialization.format=1}
