spark hive hbase 結合
spark hive hbase 結合
業務需求,需要整合需要讀取hive資料匯入hbase中,一下是環境配置流程以及中間遇到的問題
1.spark讀hive
需要copy hive-site和hdfs-site 等配置檔案到專案資源包下
object hivesql {
case class Record(key: Int, value: String)
def main(args: Array[String]): Unit = {
// warehouseLocation points to the default location for managed databases and tables
val warehouseLocation = "spark-warehouse"
val spark = SparkSession
.builder()
.appName("Spark Hive Example")
.master("local[2]")
.config("spark.sql.warehouse.dir", warehouseLocation)
.enableHiveSupport()
.getOrCreate()
import spark.implicits._
import spark.sql
// sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)")
// sql("LOAD DATA LOCAL INPATH 'examples/src/main/resources/kv1.txt' INTO TABLE src")
// Queries are expressed in HiveQL
sql("SELECT * FROM test limit 10").show()
問題1

原因是hive沒有啟動metastore 服務
在hive-site.xml 中新增
<property>
<name>hive.metastore.uris</name>
<value>thrift://ip:9083</value>
<description>IP address (or fully-qualified domain name) and port of the metastore host</description>
</property>
hive –service metastore 啟動
再次run 程式報一下錯誤

這是由於我們使用第三放jar 解析json檔案導致的
需要將其加入到你專案中可以直接copy jar 到專案add libary
或者新增到mvn中應用
mvn install:install-file -Dfile=/Users/zenmen/Documents/json-serde-1.3.8-jar-with-dependencies.jar -DgroupId=com.hive.jsonserde -DartifactId=json-serde -Dversion=1.3.8 -Dpackaging=jar

發現還缺少 hadoop lzo code
同樣的方式 找到hadoop-lzo包自己新增,或者新增對應的mvn依賴 即可解決
問題2:
java.lang.UnsatisfiedLinkError: no gplcompression in java.library.path
copy hadoop native 下的lib庫檔案後發現還是不行
查詢官網
http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-common/NativeLibraries.html
The native hadoop library is supported on *nix platforms only. The library does not to work with Cygwin or the Mac OS X platform.
我 … native library 不適用於mac os x。發現不支援,難不成還有自己編譯,雖然本地查詢hive已經沒有問題,但作為程式設計師 這是不完美的,時間原因,後續研究吧,
windows 對應的Hadoop lib
