PySpark修復/刪除控制檯進度條

Question

如下所示，Spark控制檯輸出進度條正在混淆輸出。是否有可用於關閉舞臺進度欄的配置或標誌？或者更好的是，如何修復控制檯日誌，以便在完成階段後進度條消失？這可能只是PySpark的一個錯誤，但我不確定。

(CID, (v1/n1, v2/n2)) 
[Stage 46:============================================>   (19 + 4)/24]('1', (0.020000000000000035, 4.805)) 
('5', (6.301249999999998, 0.125)) 
('10', (21.78000000000001, 3.125)) 
('7', (0.005000000000000009, 0.6049999999999996))

('7', 0.7810249675906652) 

(CID, (AD_MEAN, NCI_MEAN)) 
('7', (1.0, 5.5)) 
('5', (7.75, 5.3)) 
('10', (13.5, 6.0)) 
('1', (3.0, 5.0)) 

(CID, (AD_MEAN - NCI_MEAN)) 
('7', -4.5) 
('5', 2.45) 
('1', -2.0) 
('10', 7.5) 

(CID, (NUMER, DENOM)) 
[Stage 100:===================================================> (30 + 2)/32]('10', (7.5, 4.990490957811667)) 
('5', (2.45, 2.5350049309616733)) 
('7', (-4.5, 0.7810249675906652)) 
('1', (-2.0, 2.19658826364888)) 

它會變得更糟，有時（滾動到右）：

$ spark-submit main.py

Answer 1

你既可以禁用通過設置

• spark.ui.showConsoleProgress =假

或

• 減少日誌記錄級別的log4j.properties比INFO更高，即ERROR

相關星火jiras：

• https://issues.apache.org/jira/browse/SPARK-4017
• https://issues.apache.org/jira/browse/SPARK-18719

spark.ui.showConsoleProgress總是在星火，因爲版本1 .2，但只會在Spark 2.2中記錄。
