[HADOOP] 하이브의 LeaseExpiredException

하이브의 LeaseExpiredException

모든. 97 %로 하이브 쿼리를 실행하고 예외가 org.apache.hadoop.hdfs.server.namenode.LeaseExpiredException : sth에리스를 보여줍니다.

누구든지 친절하게도이 오류가 발생한 이유를 설명 할 수 있습니까? 그리고 이것은 단일 사용자 하이브 (Hive) 클러스터 환경입니다.

미리 감사드립니다.

해결법

1. ==============================

   1.하이브 쿼리가 병렬 MR 작업을 생성합니까? 나는 같은 문제가 있었고 그것을 발견 : LeaseExpiredException : 임대 오류가 HDFS에 :

   하이브 쿼리가 병렬 MR 작업을 생성합니까? 나는 같은 문제가 있었고 그것을 발견 : LeaseExpiredException : 임대 오류가 HDFS에 :

   작업이 끝나면 / 데이터 / 작업 / 폴더가 삭제됩니다. 병렬로 실행되는 작업이 거의없는 경우 삭제 작업은 다른 작업의 파일도 삭제합니다. 실제로 / data / work /를 삭제해야합니다.

   즉,이 예외는 작업이 더 이상 존재하지 않는 파일에 액세스하려고하면 발생합니다.

2. ==============================

   2.SET hive.exec.max.dynamic.partitions = 100000; SET hive.exec.max.dynamic.partitions.pernode = 100000;

   SET hive.exec.max.dynamic.partitions = 100000; SET hive.exec.max.dynamic.partitions.pernode = 100000;
