Elazar Gershuni commented on SPARK-12623: ----------------------------------------- At the very least, it should have a "won't fix" status, rather than "resolved". How can I suggest this change to Spark 2.0? > map key_values to values > ------------------------ > > Key: SPARK-12623 > URL: https://issues.apache.org/jira/browse/SPARK-12623 > Project: Spark > Issue Type: New Feature > Components: Spark Core > Reporter: Elazar Gershuni > Priority: Minor > Labels: easyfix, features, performance > Original Estimate: 0.5h > Remaining Estimate: 0.5h > > Why doesn't the argument to mapValues() take a key as an agument? > Alternatively, can we have a "mapKeyValuesToValues" that does? > Use case: I want to write a simpler analyzer that takes the argument to > map(), and analyze it to see whether it (trivially) doesn't change the key, > e.g. > g = lambda kv: (kv[0], f(kv[0], kv[1])) > rdd.map(g) > Problem is, if I find that it is the case, I can't call mapValues() with that > function, as in `rdd.mapValues(lambda kv: g(kv)[1])`, since mapValues > receives only `v` as an argument. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
