這會導致MR作業。 MR作業成功運行,但是當蜂蠟嘗試渲染結果時,我得到一個OOM異常。配置單元 - 內存不足異常
我想知道是否有一個配置設置來幫助我通過這個問題。

更新 我在Cloudera的經理,但沒有雪茄增加內存設置。第一次重新啓動服務後,我運行查詢它的工作原理。我運行它的第二次失敗:
- 順化 - 蜂蠟服務器(默認)/資源管理 - 蜂蠟服務器的字節[1吉布] Java堆大小
- 蜂巢 - 網關(默認)/資源管理 - 客戶端Java堆大小(字節)[1吉布]
- 蜂巢 - HiveServer2 (默認)/資源管理 - 在 字節[1吉布] HiveServer2的Java堆大小
Thanks @Ruslan。我想這是客戶端,我如何將客戶端xmx設置爲蜂蠟? – hba
您是否在使用Cloudera發行版?如果是,請導航到Hive - >配置 - >在搜索框中輸入「xmx」。第一個選項是「客戶端Java堆大小(字節數)」,我相信它默認爲1Gb。看看增加這個是否有幫助。 – Tagar
我會試一試並更新帖子... thx @Ruslan – hba
