This is a known issue with Spark REPL. You can find more details in SPARK-2620. It affects multiple operations in Spark REPL including most of transformations on the PairwiseRDDs. For example: case class Foo(x: Int) val foos = Seq(Foo(1), Foo(1), Foo(2), Foo(2)) foos.distinct.size // Int = 2 val foosRdd = sc.parallelize(foos, 4) foosRdd.distinct.count // Long … Read more
May I suggest something that doesn’t involve creating strings, copying arrays or unsafe code: using System; using System.Collections.Generic; static class ByteArrayRocks { static readonly int[] Empty = new int[0]; public static int[] Locate (this byte[] self, byte[] candidate) { if (IsEmptyLocate(self, candidate)) return Empty; var list = new List<int>(); for (int i = 0; i … Read more
In Bash you can do it by enabling the extglob option, like this (replace ls with cp and add the target directory, of course) ~/foobar> shopt extglob extglob off ~/foobar> ls abar afoo bbar bfoo ~/foobar> ls !(b*) -bash: !: event not found ~/foobar> shopt -s extglob # Enables extglob ~/foobar> ls !(b*) abar afoo … Read more
Use the unaccent module for that – which is completely different from what you are linking to. unaccent is a text search dictionary that removes accents (diacritic signs) from lexemes. Install once per database with: CREATE EXTENSION unaccent; If you get an error like: ERROR: could not open extension control file “/usr/share/postgresql/<version>/extension/unaccent.control”: No such file … Read more
It “splats”1 the sequence. Look at the constructor signature new Elem(prefix: String, label: String, attributes: MetaData, scope: NamespaceBinding, child: Node*) which is called as new Elem(prefix, label, attributes, scope, child1, child2, … childN) but here there is only a sequence, not child1, child2, etc. so this allows the result sequence to be used as the … Read more
Use awk with a flag to trigger the print when necessary: $ awk ‘/abc/{flag=1;next}/mno/{flag=0}flag’ file def1 ghi1 jkl1 def2 ghi2 jkl2 How does this work? /abc/ matches lines having this text, as well as /mno/ does. /abc/{flag=1;next} sets the flag when the text abc is found. Then, it skips the line. /mno/{flag=0} unsets the flag … Read more
Use: /(&|\?)list=.*?(&|$)/ Note that when you use a bracket expression, every character within it (with some exceptions) is going to be interpreted literally. In other words, [&|$] matches the characters &, |, and $.
FTS does not support LIKE The previously accepted answer was incorrect. Full Text Search with its full text indexes is not for the LIKE operator at all, it has its own operators and doesn’t work for arbitrary strings. It operates on words based on dictionaries and stemming. It does support prefix matching for words, but … Read more
Print lines between PAT1 and PAT2 $ awk ‘/PAT1/,/PAT2/’ file PAT1 3 – first block 4 PAT2 PAT1 7 – second block PAT2 PAT1 10 – third block Or, using variables: awk ‘/PAT1/{flag=1} flag; /PAT2/{flag=0}’ file How does this work? /PAT1/ matches lines having this text, as well as /PAT2/ does. /PAT1/{flag=1} sets the flag … Read more
