The first time I saw Spark crash.

The phenomenon of Spark Shell memory OOM

To do Spark diagram calculation, so the use of Google web-Google.txt, size 71.8MB.

To command:

Val graph = GraphLoader.edgeListFile (sc, "hdfs://192.168.0.10:9000/input/graph/web-Google.txt")

When building the graph, it was returned directly to the console after a long time of operation.

Interface xian

Scala > val graph = GraphLoader.edgeListFile (sc, "hdfs://192.168.0.10:9000/input/graph/web-Google.txt")

[Stage 0: > (0 + 2) / 2]. / bin/spark-shell: line 44: 3592 Killed "${SPARK_HOME}" / bin/spark-submit-- class org.apache.spark.repl.Main-- name "Spark shell"$@"

The second Spark crash!

Perform the pagerank algorithm test, using the data web-Google.txt of google, the size 71.8MB.

Val rank = graph.pageRank. Vertices

Spark is a cluster of master,2 worker. As a result, slave2 is down.

As a result, I have been trying to connect to slave2, hehe.
